the money isn't coming from taxpayers, it's coming from investors (who don't even have as much money as they announced they're giving, lol). it's just another bullshit deal where trump goads some powerful people into making big vague promises that nobody seriously expects them to follow through on, but it creates the appearance of success and momentum. it's hypothetical future investment. no contracts signed or anything like that. he does this sort of thing all the time, i'm surprised people still keep buying it. but the end result is that other powerful people want to get the free publicity of a trump announcement, so they also rush over to make their own big investment, trade deal, whatever. the result is some quantity of money flows into american industry that wouldn't have otherwise. how much exactly is hard to say, but it's not nothing. and that's good. but it's certainly not the amount trump got them to say. it's more about trump signalling priorities and getting businesses/countries to compete with each other for his attention.
