It doesn’t matter how long you make them read Lenin and break rocks in the gulag, the second you let them out they’ll see an AI generated meme from a CIA holdout posting from a bunker somewhere and immediately revert to being a burgerbrained fash.
I think we need to just dump them on an island somewhere and put them under continuous naval blockade and internet blackout till they revert to a Hunter gather society.
I think even the hyper wealthy could be reformed on a long enough time scale. I think time is the fundamental issue with re-education. Some chuds are going to take decades to destroy all of their brainworms. Then, it will take even longer to actually educate them.
A cultural revolution in the US is going to be a massive undertaking. You would likely have to use the newly-empty prisons and then some to house all of the chuds. It will be hours per day of classes to get them back to a baseline understanding of how the world actually works. Especially getting them to understand that no, human nature isn’t to take everything for yourself and kill anyone else.
And a lot of them will deserve execution. But we don’t do executions as punishment. We do them out of necessity when there’s too many people to try and change or who are too dangerous to be left alive.
