Google can buy cheap chips („depreciating asset“/tool) and use them to offer better services in part because the dollar is more valuable than it should be. But the American worker becomes more expensive and less eager to work.
On the other hand, foreigners move to the high paying US to work and build companies. This braindrain starves the rest of the free world of their entrepreneurs.
Some people say China or India is going to be the next super power, but those aside, I don’t see any country that is in better position than the USA.
