Magical thinking: if we just tear down everything that is and all we have been then the just society will pop out of no where like Zeus from his daddy’s thigh.
Yes, amazing isn't it?
It totally aligns with why socialism/marxism always fail....it was not tried by the right people who cares about race, gender, sexual orientation, etc.
But, in the end, it all comes down to "trust us" over what you have now. Replace those racist, greedy, hateful people with us and it will be far better.
Of course, we know it will fail again.
One big reason why these ALWAYS fail is that they are great at the distribution of things, but they have ZERO plan for production of things.
That is why Venezuela produces no oil, has shortages of food, toilet paper, etc. Socialism redistributed things equally, but collapsed the production side (due to lack of incentive and talent).
