Australia effectively scrapped this sort of visa in 2024 because it wasn't bringing the expected benefits. The UK did a similar thing because of it being exploited by oligarchs. (https://www.bbc.com/news/world-australia-68052626)
The European court of justice just concluded that Malta's golden visa program is illegal and needs to be stopped as well.
As far as I know, pretty much everyone who's tried this has ended up scrapping it; it _never_ works.
I think we are possibly looking for different benefits here. This time, it's just temporary cover for economic hardships. "The Trump cards will bring in so much money, later." Also, the point this time is to actually get the oligarchs into the hen house.
