I have an MA in Political Science (emphasis on political economy) and one in Criminal Justice. I work in the analysis of crime as a profession. There is no singular negative trend in juvenile crime in the last 50 years, let alone any that can be correlated with an external variable. I can also confidently state that you do not understand Keynesian economics, based off of statements you have made.
Also, since God was never removed from classrooms, your argument is baseless.
Because I don't subscribe to Keynesian economic theory doesn't mean I don't understand its workings. My Masters of Business Administration certifies that I do indeed understand the basic fundamentals of John Maynard Keynes' brand of macroeconomics, but I consider myself more of a fan of Adam Smith, and ergo Milton Friedman's, monetarist economic teachings. In my limited exposure to what I'm sure you are expert in, I found myself relating better to Friedman than to Keynes.
As far as the Bible in the classroom goes, compulsory reading of the Bible on a daily basis was removed, effectively removing God from the classroom. Spin it any way you want. I have also seen the statistics from that time period and going forward, and there is more than enough evidence to support my claims of a correlation, if not to juvenile crime specifically, to crime and other undesirable results:
The educational standard of measure has been the SAT scores. SAT scores had been steady for many years before 1963. From 1963 they rapidly declined for 18 consecutive years, even though the same test had been used since 1941.
In 1974-75 the rate of decline of the SAT scores decreased, even though they continued to decline. That was when there was an explosion of private religious schools. There were only 1000 Christian schools in 1965. Between 1974 to 1984 they increased to 32,000.
You just can't make this sh*t up.
