The youth always have utopian vision, until they grow up. About 20% never grow up or fail to understand the world has challenges, hence today's kids needing safe zones from reality. I'm convinced that about 15% of the population cannot handle change and change threatens their utopia. I recently saw a 2 1/2 hour show on CSN&Y, they were rocked by the reality of change and bad things, the RFK and MLK and Manson murders really forced them to see the real world and evil that ruins their utopias, they were crushed. Just like today's kids realizing they have to work, hear different opinions, pay off debts, it rocks their utopia of Mom and Dad paying for everything and them getting participation awards, never having to deal with a loss, until they do and they break.
Leftist utopia requires a population of snowflakes stripped of ambition and individualism. The USSR had eighty years to create the new “Soviet Man” and was unable to change human nature.
The genius of capitalism is like ju-jitsu. Rather than suppress human nature, it takes advantage of it. Human desire to accumulate stuff and stand out are encouraged, with government taking a slice of product generated.
Government slice has become onerous, but human nature remains human nature. Socialism can’t change that, but it can make resisting collectivization a slog. Eventually, the cycle completes and the Tree of Liberty gets watered.
