Hmm,i wonder why i as a non immigrant don't qualify for this citizenship even after paying all taxes, including FICA
Salary taxation usually means you are earning your dollars by being part of a functioning society.
There are billions of people who would happily become "subscribers" to a US job market, even if the offer required that 50% of their income was ritually burned for no benefit to the “subscriber”.
Now capital gains are perhaps a different argument…
