Ah, education is an interesting point.<p><i>The question is why don&#x27;t other countries tax their citizen abroad?</i><p>I assumed that the general consensus was that it all balances out at the end of the day – countries don&#x27;t tax their citizens abroad, but do tax noncitizen residents who have income in the country. Either approach isn&#x27;t all that bad, but it&#x27;s interesting to think about how it can realistically be handled where individuals can hold multiple citizenships. My partner is dual US&#x2F;UK, and completing a US tax return when you haven&#x27;t lived in the country in decades is expensive and time-consuming.
