I think when you look at history it doesn't predict the future, but it tells you what is possible.
What we had is possible, it did happen. Why? What was the system of alignments and incentives that led to that being the case, and how are we different now?
I do think that if you want to bring back asylums, a place to lock away people who are too expensive or are otherwise uneconomical to treat, you must have an answer.
Talking about taxation in America is a political death sentence. Privatization of public services is still extremely rampant. How are you going to get well run asylums if you can't tax or you have a for-profit model?
If you want nice things, we have to be getting less corrupt as a country, not more corrupt, and we are most definitely getting more corrupt. I absolutely do not want asylums as long as we are inching towards literal oligarchy, and we definitely are inching closer to it than farther away. Our supreme court justices openly take bribes, and our representatives think it's ethically okay to trade stocks. Our politicians are choosing to carve up districts to keep themselves in power, and some want to absolve the idea of voting altogether and just choose federal candidates from state legislatures.
Asylums are running when we can't even walk. The post office was in the process of being dismantled to create pretext to steal an election and you think we can run an asylum?
Do you really want an asylum in the context of Ron DeSantis's Florida and GOP rhetoric against trans people? That seems like a bad mix.
Those that fail to learn from history are doomed to repeat it.
