Americans abroad are burdened with not only dealing with the tax rates of the country they currently inhabit, but also from the United States despite not earning their income in the U.S.
Americans over the years have chosen to make the tough decision to revoke their citizenship just to keep living in their current country of residence.
The U.S is one of the few countries still practicing this and that needs to change. People give up their citizenship over this dilemma and I know there are people out there still making that tough decision.
