God did not create the current system of government on the seventh day of creation. The current system had to defend its existence (or rather, creation) at the time of its origin.

The thing about criticism is, we're a long way from "the worst possible outcome". That is, there is a lot that the current system gets right.

Oh, you don't have one? Yes, it's still valid to point out that there are problems. It's valid to demand that we not become complacent with the current problems. That's not wrong.

No, neoliberalism is only 50ish years old and all it did was usher in nascent fascism and income inequality.
