Good point. But at the same time, reality dictates that only certain countries could export such and such because of climate and geography. You mentioned pineapples, they could only be produced in tropical countries because that’s where they could only grow. Of course, that will have to undergo an expansive supply chain. Oil is also only in certain parts of the world. These things will have to travel across the world.

You’re not wrong about worker exploitation. But unfortunately, many governments of third world countries actually negotiated for Western businesses to set up shop with them to provide jobs for their own population. They offer cheap services in exchange for high capital and return on investment. However, as these countries become richer, they are also increasing their demand for higher wages and better treatment. Foreign companies then would relocate to another country to continue the cycle, until they run out of countries for cheap labour. That’s why companies would love AI and robots to develop more, so they don’t have to pay for expensive humans.
