The funny thing about it is that, during the McCarthy era and a time when there was practically a national panic over "godless communism," the thing that bugged people the most was the "godless" part. However, people still supported better wages and working conditions, and overall, the standard of living improved for working people during this period. The U.S. was far more supportive of labor unions back in the 50s and 60s, too. When I was a kid, our family didn't have to pay a dime in medical bills or insurance, since employers paid for everything back in those days. Schools were also far better, relatively speaking.
So, back in those days, America was very decidedly anti-communist and actively engaged in global containment of international communism, yet far more friendly and decent towards working classes and was far more amenable to reform (such as the Civil Rights Act and LBJ's Great Society). But by the Reagan era, capitalists did a 180° turn and made a concerted to try to undo most of the reforms of the previous 40-50 years.
America was doing fine, and capitalism was doing fine, until Reagan, Greenspan, et al., decided to screw it all up - and for no other reason other than blind, unmitigated greed. That's why I oppose capitalism now. A Keynesian, liberalized model of capitalism (such as under FDR) would still be capitalism, but capitalists won't even compromise on that. They won't even agree with minor tweaks, like wage and price controls. From my experience, many (if not most) capitalists have become far too stubborn and intransigent in the past several decades, unwilling to accept even moderate reforms.
