The United States and Eritrea are the only countries in the world that tax their citizens when they reside in another country. American Citizens who live and work abroad are left at a disadvantage, having to file incredibly complex federal taxes (it is a more complex form than the one used in the US ) yearly without receiving any of the benefits that those taxes pay for. The US has been using this system for a long time but there was little effort to enforce it until recently with FATCA. This law effectively bullies the US's closest allies into paying to enforce our laws. It will cost our allies more to enforce than it will collect for our government. It will also reinforce our reputation as a bully and americacentric.
