It's funny that everyone is saying that the US lost its mojo, but nobody with power actually wants the US to actually have any mojo. It would involve the capitalists sacrificing their wealth in order to actually develop stuff I guess.

Of course the US is still great at advanced technologies. Launching lots of rockets, doing fancy scientific research, designing integrated circuits, and so on. But that stuff mostly matters for military imperialist stuff, it doesn't always come to the US directly in the form of improvements to quality of life.

It's okay, once the US launches the Third World War and wins it, we'll have free healthcare and all that.
