    Hah I've never seen anyone so right for such the wrong reasons. There are lot of parallels between the 20s and subsequent depression, and the 90s, and the subsequent series of recessions. It started with an inflated stock market, inflated real estate markets, heavy debt spending by consumers, stagnation in working class wages while white collar workers cleaned up, unequal income distribution, huge salaries for the CEO class... as for turning against god, we are no more for or against god now than at any other time in our history Edit: Ah, sorry. I didn't realize you were asking the question only of people that already agreed with your answer. You should indicate next time. Use "Christians Only" or some other qualifier..
