Just want to make a note on this.
The reasoning behind the idea that high productivity = high wages is that employers pay employees what they are "worth" according to some standard based on how much a worker can produce. That isn't the case. An employee is paid what the employer has to pay to get the necessary work done, and like all prices this is set by supply and demand. Increased productivity, by reducing the demand for labor, tends to drive wages down, not up.
Now, it also increases the supply of goods, which can drive prices down, too, so the net effect may be a small increase in employee buying power (or effective wages). But the result over time is an increasing decline in the wage/productivity ratio, which is where a capitalist economy breaks down.
That doesn't make increased productivity a bad thing! Obviously, as productivity rises, the economy as a whole becomes wealthier. This, coupled with good distribution of wealth (and there's the rub), gives us higher consumption or more leisure time or both. But the tendency is for the gains to concentrate at the top, among the owner class, which prevents the potential from being realized.
In the long run, as M&L said, the only way that distribution will be possible is through a socialist economy, in which most people are unemployed (but quite well off), and paid through a socialized owner's share of the means of production. The image is of a population whose needs and wants are supplied by machines, and who devote themselves to art, science, entrepreneurship, or in many cases simply to play.
It's either that, or a capitalist economy in which most people are unemployed (and quite poor), and paid through miserly government welfare out of a severely contracted economy that operates at a tiny fraction of its productive potential. And that is a situation asking for a revolution.
