So it still doesn’t explain why the US is the only one that charges tax on foreign-earned income.
On the wealthy…
You keep omitting that point, and it’s starting to get old.
But the reason is idealistic.
America was supposed to be the land of immigrants where anyone can immigrate, work hard, and earn wealth.
That system doesn’t work if once you amass your wealth, you fuck off somewhere else and take it all with you. The reasoning is you were able to amass that wealth through America’s social ladder.
If the wealthy (the only ones that pay foreign income tax or exit taxes) don’t want to pay that, they know that being honest will never result in change.
If how I’m saying it doesn’t make sense, use the IRS website I’ve provided numerous times.
