From my understanding, please correct me, is that America(tm) requires that you never _save_ money by leaving the country and working somewhere else.
Say your US tax rate is 27%, you are working in Canada and your tax rate is 32%, you pay Canadian taxes first, then file with the US which charges you nothing.
If you are working in a place with a 5% tax rate, you will owe the US the difference. When you are a US citizen, your global minimum tax rate is your US tax rate. You can never save money on taxes by leaving the country, only by giving up citizenship.
You can save money on taxes by living somewhere with a lower cost of living, make less, spend less.
