Surely if the US wants to deny citizenship to people most likely to use benefits, it's going to have to start removing current citizens, not immigrants? Given that immigrants in the US are "less likely to consume welfare benefits" (src).
Wait, does welfare and benefits cover all government money going to private citizens? Because the US Government has had to pay Trump millions of dollars every time he goes golfing (and he promised to go golfing less than Obama did, he failed).
