wishful thinking mostly. it's a form of escapism/fantasizing about a better future, rather than actually dealing with the complex problems of ones current reality.
just like a lot of poor people gamble their disposable income in the hope they will become rich, because saving it and investing it is too abstract/difficult of a concept for them. and the momentary hope/high of the activity is provides immediate gratification.
where as richer people see gambling as a leisure activity, they don't see it as a path to riches. they understand getting richer requires saving their income and investing it and waiting for the payout 10-20 years in the future when those investments double/triple in value.
I mean, I was super into communist/anarchistic when I was a teenager. Then I went to college and realized the world is way more complex/chaotic than anything those theories can cope with, and most theory is really. But generally I prefer theories that acknowledge the basic truths of reality and don't pretend there is a ideal form of anything.
