It is a very simple concept. Rice can be made here and is made here. To make rice in the US is very expensive, some of the most expensive crops we can raise here. In China, their climate is much better suited for it and their mode of production is cheaper (labor costs). If we only consumed US grown rice it would be scarce and super expensive. We export much of our rice and we profit from it, meanwhile we import Chinese and Asian rice because it is so much cheaper. This is logically sound and financially smart. Are you willing to work in a rice field at minimum wage? We can't have a strict labor immigration policy, high minimum wage, AND consume our own crops. That is not sustainable.
