Don't forget that most hippies were alpha males, or at least from well off families. The free love culture passed my parents by as they were too busy making a living.
Your parents let it go by and it doesn't prove the rule.
The culture permeates every level. The "alpha male" culture benefited most men in 2015-2016, even if they didn't capitalize on pointless sex. The free love movement expanded it's own movement into most parts of the culture. These patterns aren't 'optional forces' that only the rich have enough spare time to participate in.
The culture force of elitism is the current phase and idolizing the rich is eternal in america.
