Didn't go well for South America in the 60s and 70s but perhaps, as economists are prone to saying, "this time will be different".
The fact that a handful of individuals have half a trillion dollars to throw at something that may or may not work while working people can pay the price of a decent used car each year, every year to their health insurance company only to have claims denied is insane.
This is disputed [1]. In reality, a handful of individuals have the capital to seed a half-a-trillion dollar megaproject, which then entails the project to raise capital from more people.
