Just imagine this.

William does not want US citizenship.

But someone else, for example from Afghanistan, takes up US citizenship.

If ████████████████████████████████████████████, compared with William:

Would the United States be expected to ███████████████████████ to protect William or the other (new) US citizen?

This, I believe, is one real impact of FATCA.

We need to see how US greatness is accreted, not eroded.

I think it has been exploited and has caused problems for many people.

People sometimes point to celebrities such as Rosie O'Donnell, Ellen Degeneres or George Clooney or to California policies in discussions about how laws like this are applied.

I fear billionaires in California feel threatened by populist politicians, who mob them for percentile targeted tax surcharges; they are considering fleeing to Florida or elsewhere to avoid unfairness, as they don't want to pay more than their fair share of what they owe (back to the) society they fed, healed and paid.

I would support repeal or, preferably, replacement with a more effective law.
