Immigration restriction in American history took both ethnicity and fitness into consideration. Reason being, aliens of non-NWE descent over-occupied jails, asylums, and shelters. Their crime, dependency, and insanity was twice and more the native rate.

Illiteracy and retardation was highest amongst South and East Euros, many of whom still can't assimilate. Ethnics such as “Italians, [Slavs], and Asiatics” were highly injurious to America, hurting our wages, ruining our cities, and degrading the mental and moral quality of the nation.

America responded, albeit too late, with laws banning the Chinese, stupid, perverse, anarchic, dependent, mentally ill, sick, and non-assimilable—laws we must invoke today. Trump's senior advisor, Stephen Miller, has noted this. He worked to end H1B visas and backed the RAISE act to block over 50% of all legals. He helped impose a wealth test to deny poors, and sought legislation to exclude non-English-speakers. Miller also had a role in the Travel Ban, barring Muslim entry.
