bit of a hazard as well. For example, let's say the loonies shouting around Portland get their way and we become the first state to institute UBI (not mocking UBI, mind you, just using it as a prop).
In a 50 state model, what's to prevent everyone from moving here and bankrupting the government, absent some other control? We don't have borders (for good reason...uh...yet), so you'd have to have some sort of test lest everyone pile in.
We're currently experiencing this with homelessness. People see us as "soft" and we get the good and the bad, the tired and poor, the drug addicts and the antisocials.
Conversely if a state has stricter taxation and one does not, you get things like Bezos declaring his existence in florida to avoid Washington's taxation ideas.
I wish I had a better idea than "make it a federal issue!" because as you said, not everyone is best served that way. However, leaving it to the states leads to odd disparities when mobility is a factor.
