Many immigrants (and their children) in the United States send money to relatives in foreign countries. Highlighted in the image below are some of the amounts sent to Latin American countries.
These are significant amounts that these countries are receiving. Many of these countries are highly dependent on these resources. Remittances to El Salvador, for instance, account for nearly 17% of her GDP.
How much are Americans sending overseas? In 2012, the amount was $120 billion.
Given the limited usefulness of this to Americans, the fact that foreign labor is already undercutting American employment, and that many foreign 3rd world countries are dependent on this money (and neglecting to build up their own economies as a result), ought we tax these payments to discourage such transfers?
