But when you let billionaires take over that too then the people have zero protections from exploitation.
If they cared they would invest in America paying more taxes, ensuring citizens are educated and capable of leading their companies versus offshoring and even competing with them.
They don't want that and prefer their monopolies instead.
And as an aside, let's deep dive into the kind of person Larry Ellison is. Guy literally bought out an island where he rules as almost-a-king.
