To me the turning point started in the later half of the 60s as the antiwar protest strengthened. It was like my generation and then progressively younger generations who collectively thought that they knew more than our parents (who did things like fight WW2 and a real depression) and became strong enough to start a change in the country. It was like a downhill ride - slow at first, but it's really out of control now. Men who died in WW2, if they saw today, would be shocked (disheartened) to see what they gave their lives for. We've made wondrous strides in technology and many other facets of life, but as a country we've hopelessly lost our way.
