That's theoretically a good thing. If it costs less to eat rice from the US, then that capital can be put to use in other ways. The problem can be an existing large imbalance in income producing resources. If rice agriculture is the only thing available, then wealth imbalance can/will increase and power dynamics start looking like oil or natural resource rich countries.

If, on the other hand, people are able to eek out improved standards of living, in general, with savings on food costs, they can increase health and education spending and get into a virtuous cycle of increased living standards.

There's a bigger context necessary.
