Ah, education is an interesting point. The question is why don't other countries tax their citizen abroad? I assumed that the general consensus was that it all balances out at the end of the day – countries don't tax their citizens abroad, but do tax noncitizen residents who have income in the country. Either approach isn't all that bad, but it's interesting to think about how it can realistically be handled where individuals can hold multiple citizenships. My partner is dual US/UK, and completing a US tax return when you haven't lived in the country in decades is expensive and time-consuming.
