The problem is that folks see these things implemented in the past and say “let’s just do that.” Why can’t we take the good parts and think beyond the rest? These are systems that just won’t work with current population growth and resources. We can always do far and away better than capitalism, but I’ve talked to a handful of working class people that lived under communism for years and they have nothing good to say about it. Not a single positive thing. It’s easy to dream about these things and wax poetic when you don’t experience them firsthand.
Any time a path opens to seize power, humans fill that void regardless of what they believe in. Now suddenly we’ve traded authoritarian 1 for authoritarian 2. It makes no sense to me and I read both Lenin and Marx.
