I would have picked ethical double standards -- soft ethical standards for some that include the right to lord it over others but harsh ones for the powerless. Such is a foundation of ruin and rebellion.
"Greed" and related vices, especially among our economic and bureaucratic elites; trickle-down economics that keep mandating greater sacrifices from the powerless on behalf of people who can treat everyone else badly; and "egotism, pride, selfishness, arrogance" that appear as destructive manifestations of a cruel and destructive economic order combine as the signature of contemporary depravity in America. These can and will bring us ruin and will put us at risk as a nation until they abate.
The profit motive (so long as it gets people to serve humanity better) and the work ethic are all to the good; without those nobody would ever invest in a coal mine and nobody would ever work in one unless at gunpoint. But when it serves only to enrich an entrenched elite through the oppression of workers and the elimination of competition it is a way in which to reward people for exercising economic power to the detriment of the rest of humanity. Free markets? We do not have a free-market economy. Much of it seems directed at ensuring that the "right people" get whatever they want.
The greatest evil is not now done in those sordid "dens of crime" (or) even in concentration camps and labour camps. In those we see its final result. But it is conceived and ordered... in clean, carpeted, warmed and well-lighted offices, by (those) who do not need to raise their voices. Hence, naturally enough, my symbol for Hell is something like the bureaucracy of a police state or the office of a thoroughly nasty business concern."
