What were the social classes of the 1960's?

Social classes can be seen as a pyramid. At the bottom the lowest social classes, and at the top the highest social classes. The ones lowest on this social class pyrmaid of the 1960's were the slaves. They had no rights or freedom, and therefore they were the lowest. One step higher up were the hippies, still not much rights but they were treated better than the slaves. Then there were the low paying workers, that had a job but got very little money. Next there was the middle class. Normal people that had a good job and got enough payed, like you and I. One step higher were the high paying workers, that got a lot of money from their job. But even better was the government which was on top of everything.
