“So long as freedom is maintained, it prevents positions of privilege from becoming institutionalized. Freedom means diversity, but also mobility. It preserves the opportunity for today’s disadvantaged to become tomorrow’s privileged and, in the process enables almost everyone, from top to bottom, to enjoy a fuller and richer life.” – Milton Friedman.
A socialist society advocated by Sanders becomes an ossified one. The free market is not perfect and not advertised to be, but is still the only way known to man to provide equality of opportunity and the most effective way to ensure that people can escape poverty.
