This is all leftover theater from the 2T...the "concern" of an impotent Congress, the warnings from the military, the necessity of not losing "face" overseas, the protests and counter protests, a President with advice from the "Best & the Brightest", land war in Asia, the superiority of our weapons, the building of "democracy" as a goal.

Ah, but in the environmental debate there is little talk of laws. There is mostly talk of regulations. I think there?s a difference. Environmental regulations take the form of sweeping, top-down initiatives designed to mitigate compound effects directly caused by government?s failure to protect individual property rights.Originally Posted by Brian Rush
Society is a collection of individuals, each of whom possess inherent rights of person and property. Any competitive practice which infringes upon the rights of individual members of society can be most efficiently corrected by upholding those individual rights. Our current trend towards replacing the individual rights of our citizens with sweeping regulatory protections goes counter to how the environment itself works.
As I?ve made clear, I am not an environmental expert. But I think everyone here would agree that the environment is not an organized system of pre-programmed design. It is more a dynamic parallel processor of complex interactions and minute corrections. I think I could argue that our biosphere operates in the same way everything in this universe operates. A basic unpredictability, i.e., free will, in the actions of each individual (be they quantum particles, paramecium, or human beings), corrected for by a trend toward what is successful for each classification of individuals (species), which in turn is dynamically influenced by further interactions ensuring that all contribute to a constantly fluctuating balance. Whew! Human interactions, including economic transactions, work along the same lines, as does everything in this universe. I realize I'm throwing a whole lot of everything into the pot here, but I'm trying to draw upon fresh paradigms. Parallel processing is the best model we have right now to describe the biosphere, economics, and human/environmental interactions, IMHO. Envision a three-dimensional, many playered game of Go.
So to apply regulation in any sort of top down manner should, and does, fail in the long term. It just goes counter to the way things really work. To be most effective, laws must reflect the dynamics of life on this planet. They must apply themselves to the characteristics of the individual members of society by protecting individual rights. If applied so, laws will quite independently protect the good of all. Put in the context of this discussion, if our government had not abandoned individual property rights in exchange for what is essentially an easement granted to industrial polluters, we?d be better off today. To attempt to solve the problem in the same way it was created seems illogical to me.
This (above) strains the boundaries of common sense. Higher wages become meaningless in an inflationary economy. An inflationary economy is exactly what you describe. ?Wealth at the top? translates economically as cash reserves, which functions as investment capital, which drives innovation, which creates employment, which fuels productivity, forever and ever amen. Simply spreading the wealth around is a meaningless notion because it doesn?t take into account the elusive nature of value. Ask the former Soviets if you don?t believe it.Originally Posted by Brian Rush

I beg to differ with you. There are environmental laws, just as there are safety laws. Regulations are how these laws are applied. In many cases there aren't even regulations. The usual situation is business negotiates with the regulatory agency to find an interpretation of the law/regulation that makes sense and that we can live with.Originally Posted by Suz X
For example my company didn't bother to comply with the Clean Air Act of 1970. Then in 1990 we had a consent judgement found against us and we had to go around and put LAER (low achievable emission rate) on everything. We spent $80 million putting in state-of-the-art pollution control and we plummetted off the list of the state's biggest pollutors.
We were also required to produce a report for the state environmental regulatory agency that characterized the VOC (volatile organic carbon) content of our fermentor exhaust. I was assigned this project as part of a larger team (mostly managers, an analytical chemist's and my labs did all the work and I wrote the reports). We went to the Capitol to get approval for the methodology we wanted to use for the study. When the meeting started the regulatory folks were spitting fire, but by the end of the negotiations they we eating out of our hands. The report was done, we identified 67 different VOCs (at very low levels) in the exhaust gas. We also investigated a whole range of control technologies. In the LAER report, I successfully argued (i.e. the regulators thought my conclusions were technically sound--regulators are often very reasonable folks) that LAER for our fermentors was no control. This saved us big bucks. Nobody else in the industry has any fermentor VOC controls, but they have followed the law since 1970 so they had no consent judgement (we were required to consider LAER for the fermentors because of the consent judgment).

I agree with Virgil. Good heavens, I've been offended by everyone here at one time or another, and from all sides of the political spectrum. There is healthy debate here (at least most of the time it's healthy), and at a very high intellectual level.Originally Posted by Virgil K. Saari
Let's face it, anyone who's gotten through the Strauss and Howe books is going to be pretty bright, and those who then take the time to find this forum and then post are going to be pretty opinionated as well. I'm surprised we do get along as well as we do sometimes.
I undoubtedly stepped on a few toes when I was getting used to this place, and I've seen others who have come after me do it, too. It's the nature of the Internet beast. ;-)

No doubt! I personally suspect that Mr. Rush would wish to see the President forced to back down, such that not only is there no war (for the time being), but Saddam Hussein remains in power, and all sanctions are lifted, including the prohibition against him developing and amassing WMD, including nukes. Said retreat should lead to a far leftrist Democrat sweep in 2004, followed by Hussein using his newly developed nukes to gain control over all the Gulf Oil Fields, and then place us under a permanent oil embargo - which he then expands to a total UN trade embargo against us (likewise permanent) with a combination of oil and nuclear blackmail aimed at those few nations who would still be reluctant to vote in favor of such a course of action. Then, with luck, our economy would implode, and the extreme leftists still in office could then scrap whatever's left of the Constitution, and turn the US into another Stalinist horror show. Of course, I don't expect any part of the above nightmare scenario to unfold, though I honestly do believe that Mr. Rush would not mind one bit if it did.Originally Posted by Marc S. Lamb

I think you misread what I said. I was not suggesting that we "leave Saddam alone, for now." I do not agree with that at all. That is why I did not go out to join the protesters. As I said, they are for leaving Saddam alone and also back the idea that the United States ought to demilitarize. That's just plain crazy. I think even the suggestion of such sends the wrong message to the Bin Ladens and Saddams of the world.
What I was suggesting, though, is that the protesters do have their uses. Even the United Nations has its uses. It seems to me that the Bush admin is using the United Nations and the weapons inspectors in order to position the United States for the coming confrontation. It is better for us if we can get the agreement of our "allies" (perhaps diplomatic sparring partners is a better term?) or at least not have them actively oppose or obstruct us in the coming war. For their part, except for England, they seem to be positioning themselves so that they can wash their hands of it if we do poorly and so that they can claim credit if we do well in Iraq. Kind of like the French, who single-handedly "won" WWII.
I don't know what you mean by Saddam's "kinder, gentler" son. They guy appears to be a psychopath. In any case, since his daddy is doomed, he's not going to be an issue.
What I was asking you all to comment on is the role of the X-ers in slowing down the righteous Boomers (and they have been righteous for a long time) in order that the crisis age well. Calling the boomers "puerile" is not much of a discussion point. Perhaps they are, but then, if you think so, with one of them at the head of state, that ought to worry you.
Rather than leave it at that, perhaps you could elaborate.

Saddam's "kinder, gentler" son makes his daddy look like an angel, Ms. Levin. That was the whole point of my stupid post.
Anyway, you've got your eyes on a bunch of Marxist leftist protestors, Ms. Levin. As usual, with their ridiculous show otherwise intelligent people are distracted from reality and into fantasy. Sheesh, this stuff gets so old.
Your so-called "role of the X-ers in slowing down the righteous Boomers" is quite silly, if I don't mind saying so. And it is sooo very, very... Boy we really do overestimate the "power of the young." And S&H really do perpetuate this silly myth.

I'm sure you're right, Mike. It only makes sense that the people who actually have to make things work do so reasonably and efficiently. My husband used to work for a nuclear power plant doing computer modeling. He says that, while the regulations were often unwieldly and difficult to interpret, the people in charge of enforcing them were reasonable and helped to keep everything moving forward.Originally Posted by Mike Alexander

[quote="Marc S. Lamb]
I disagree, Mr. Lamb. I know quite a number of people who are not at all Marxist nor are they on the left and yet they oppose this war. Many of these people are members of the military and so were not on the streets last Saturday. They are the ones who will be putting their lives on the line, Mr. Lamb, as they volunteered to do, and they are opposed to this war for reasons that have nothing to do with Karl Marx. There were also numerous organizations that sponsored the protest and they were not all leftist and/or Marxist.Anyway, you've got your eyes on a bunch of Marxist leftist protestors, Ms. Levin. As usual, with their ridiculous show otherwise intelligent people are distracted from reality and into fantasy. Sheesh, this stuff gets so old.
Mr. Lamb, as you commonly do, you have provided a lot of adjectives but no substantial arguments to support your claims that the protests are a "ridiculous show" or that they "distract" people into "fanstasy." You may indeed be right but unless you provide arguments and evidence for your claims, I will not be persuaded.
Again, Mr. Lamb, you make the claim that my question for discussion is "silly" but you did not provide an argument. I do not accept name-calling as an acceptable replacement for a good, well thought out argument. If you were one of my students I would write "glittering generalities" in the margin and ask you to support your assertion.Your so-called "role of the X-ers in slowing down the righteous Boomers" is quite silly, if I don't mind saying so. And it is sooo very, very... Boy we really do overestimate the "power of the young." And S&H really do perpetuate this silly myth.
As it stands, I can tell that my question created emotion in you and that you responded by name-calling but that is all I can glean from your diatribe. I am guessing that you do not like the protests and/or the protesters.
At last, a good topic sentence. Now, support that with discussion and at last we can communicate!If anybody is "slowing down the righteous Boomers," Ms. Levin, its Silents like Colin Powell...
