The "no food in other countries" is because of failed/corrupt governments, not because people use AI to generate cat pictures in the West. The economy is not a "fixed pie" that needs to be allocated among people of the world.
Just look at Cuba, which could be a very rich country and one of the prime tourist destinations of the world.
Both of those problems exist largely or primarily due to the US, destabilizing countries with bombs and coups, and the cuban blockade.
