The FEIE and foreign tax credits are just there to limit the scope of double taxation, and often they can't even do that much. Then you have to consider the cost of compliance, requiring specialist tax advice encompassing two countries; the difficulty of obtaining financial services because of FATCA; the frequent impossibility of saving for retirement because of the way the U.S. treats foreign investment funds (PFIC).

There's a reason no other country on earth tries to do this.
