My issue isn’t so much with the tax itself as it is selectively enforced. If those assets remained in the US and the person never renounced, they would never be taxed. Or at least not taxed at the same rate.

So it’s important enough to make sure rich people don’t run away but, as long as you don’t try to run, you don’t owe us anything… So the rich in America can continue getting richer…

Also, the income threshold is pretty average for any senior level software engineer. You don’t need to be astoundingly rich to be on the hook.
