The most competitive export of USA is the USD
There is no need for education, babies, manufacturing, because all of it can bought by minting USD. Babies can be imported. They come ready to pay taxes full educated, we call them immigrants.
Only USA can mint risk-free USD in the world. The rest of us only have access to risky re-hypothecated offshore USD liabilities
Why does USA need nuclear reactors? Just mint USD and buy energy.
