Let me put something into perspective. America advocates markets and meritocracy and fixed borders. This sounds very ‘moral’ but it is just profitable for an advanced country to advocate meritocracy. For the same reason it is sensible for a less advanced country to advocate authoritarianism.
We all pursue self intersets. It is just that sometimes, self interest is in everyone’s interest. And America’s self interest is most often in everyone’s interest.
It’s not because americans are good or smart.
it’s because it is more profitable.
