In some ways, they actually did pretty well, and I loathe the Boomers so that's hard for me to admit.
On cultural issues, the Boomers really have made a difference. Above a minimum standard line of education and awareness, most people now are not racist or misogynistic or homophobic. They're actually better people than their complements were 50 years ago.
On economics they completely dropped the ball and let the Plutes destroy the country, no question. They were so concerned about social improvements and tolerance that they took their eye off the real enemy, and now inequality rages and the 1% have f-cked the nation to within an inch of Third World misery. But that is remediable far more easily than the inborn, inbred hatreds that animated most people up until just a few decades ago.
The hemlines of economic theories rise and fall -- as long as we can remain a democracy we'll fix what the Boomers destroyed when they turned to Reagan and his fools. The cultural advances are hopefully permanent. We're not going back to the hellish bigotries of the past. If a quarter or so of the population will never rise out of them, so be it. We will cordon them off as a wildlife preserve, occasionally raiding it to carry away a few of their better looking, less disease-riddled daughters.
Aren't you a Boomer?
