I suspect “businesses” are different from “individuals”.
Indian immgrants send big money back to India, just as Mexican immigrants send big money back to Mexico. These are big sources of wealth for the sending countries.
I suspect the reverse is true for “companies”. A Mexican company invests in Cement Ready Mix trucks in the US and is a net investor in the US. The same with India. They invest in the US.
The free market is the ideal and would be the goal. But when one country acts to limit the free market, how can the other country react without also limiting the free market. Mutual assured destruction is the result.
My bad..... may have conflated the two.
