Good Question. I don’t have a definitive answer, but I think that the second act showed that, even though the punishments where less immediately severe, the people were still unhappy. The seventies where the morning after period of the sixties, and after the honeymoon was over, it was clear that sex doesn’t solve everything. The Sixties were a vital stage, and the greater freedoms allowed people to ask the questions of society, but ten years latter, the people had realized that freedom wasn’t the final answer, and that there is no final answer to be found. We just have to try and find what works, and carry on.
