# How is sending money out of a country draining its economy?

Every year, Mexicans working in the U.S. send at least $20 billion back to Mexico in the form of remittances, placing a huge drain on our economy. But I don't see what negative effects it could have on the US economy. Won't the money find their way back to the US, since that is the only place where you are able to trade them for goods and services? Would the impact be different for a smaller country with a currency not as global as the US dollar? • People in Mexico spend money on goods and services largely produced in Mexico, some from the United States and some from the rest of the world. Exports are in fact a drain on the economy (you spend resources to produce something you do not consume) but are offset by the benefits of imports (stuff you consume without having to produce) and when trade is voluntary this is a mutually beneficial exchange. But in a sense this is the wrong question: if remittances were prohibited then would be fewer migrant workers, so the United States would be poorer without them. – Henry Aug 25 '17 at 9:10 • 20bln remittances are drain on the US economy? That's not a good argument, must be coming from Trump supporters! It is a$20 trln economy. – london Aug 26 '17 at 0:19
If you want to explore a case of a small country with large remittances, I believe Qatar is one of the big outliers out there, where the migrant population is 88% of the total population of the country, sending $11B in remittances in 2016. Whatever money earned in a country that is spent outside that country is taking away economic activity from that country, GDP can no longer be increased with that money. Sending money to a country with a different currency usually implies that currency is bought. That will increase the value of the bought currency and decrease the value of the currency sold. A lower US dollar will make it easier for US exporters to sell their products abroad, which will lead to foreign importers selling their foreign currency in return for US dollars. That is how the money can come back at some point. It can also come back if foreigners invest in the US. If the US has a lot of money from remittances flowing out and doesn't export as much as it imports, which has been the case for a long time, foreigners holding US stocks and bonds will be the result. You could argue this could lead to a dangerous dependency at some point, e.g., if you look at how much the US owes to the Chinese. Mexico in comparison is too small an economy to be such a threat and I agree with the comment above that losing a significant number of Mexican workers would be much more problematic to the US economy. You should also take into account that the positive development effects of remittances in the receiving country should that country to become a more attractive partner for trade with the sending country, especially given the strong relationship that is built by the migrant community. • But one gigantic source of cross-border monetary flow is US government debt, since about 1/3 of the debt is bought by foreign parties, using US dollars that are then not available to purchase US goods. Taking \$1T a year as the approximate increase in federal debt (it varies widely), about \\$300B is "exported" annually. This easily swamps whatever effect (real or not) the Mexican remittances create. – Hot Licks Sep 25 '17 at 2:08
