The US is really awful about this. Americans are not allowed to opt out of their citizenship without extreme measures.

Maybe that wall isn't for keeping Mexicans out?

False. If you renounce it it's expensive and difficult to get it back, and but renouncing itself is free and unilateral.

To sum up, there was a $450 renunciation fee as well as a $450 fee for relinquishment, but both were jacked up from $450 to $2,350. This does not include exit taxes and the like, but while $4700 might seem trivial to the well-heeled, it's a far cry from free (and unilateral).

Thanks for catching my error.

Which is a common reason to wish to renounce US citizenship. But there is a trap which prevents renunciation because you don't like to be unfairly taxed:

"If the Department of Homeland Security determines that the renunciation is motivated by tax avoidance purposes, the individual will be found inadmissible to the United States under Section 212(a)(10)(E) of the Immigration and Nationality Act"

Which seems perfectly fair to me.

Or to the aging of the infrastructure?

When I go on holiday, am I obligated to leave my water turned on? My power? My cable service? Or can I turn it off, and come back?

Fun fact, for many immigration classes, a US citizen is required to sign a security document saying that even though you are paying SS and other taxes, that the government, for ten years, may come after them for every dollar of benefits you may claim.

So an eighteen year old who has yet to pay taxes can claim these benefits, but a thirty year old immigrant has to pay taxes without access to services for ten years (well, with access but with the government reserving a right of recovery for any use).
