FATCA made it impossible for an American to have a bank-account abroad [1]
PFICs made it impossible for an American to invest in non-US funds [2]
Together with world-wide taxation, punitive departure tax when renouncing the citizenship and huge estate tax when finally passing away, seems to me that Americans are becoming prisoners of their own government.
