A rat’s rear end?
Until the late nineteenth century, The U.S. didn’t even have immigration laws, and the first ones, like The Chinese Exclusion Act of 1882, were largely racist and specific to certain types of labor.
The general Immigration Act of 1882 “levied a head tax of fifty cents on each immigrant and blocked (or excluded) the entry of idiots, lunatics, convicts, and persons likely to become a public charge.” You can bet that lots of those got through, however. Frederick Trump (or maybe Drumph; it is unknown when the name was changed) was in the category of “likely to become a public charge,” since he had no job and no income.
He was allowed in however, like millions of others who came here to better themselves, and it is their progeny who now have decided that no more can be allowed, since the nation is becoming too diverse, and this is a threat to their white ruling status.
Just more of the “I got mine, you can go to hell,” philosophy of the right wing and fascist rulers.
