Most and I say well over half of today's legal immigrants would have never been allowed to enter America before 1965.
Before the IRA of 1965, America's immigration policies were what was best for America not what was best for the immigrant or one particular political party.
Here's one rarely brought up.
How many legal immigrants couldn't make it in America and gave up and returned to their former homeland ?
Since there was no such thing as entitlements and welfare in America before WW ll, if you failed you were on your own. The choice was either returning home or resorting to crime.
Since there were no records kept on how many immigrants returned to their original country of birth only estimates can be made by comparing census records and ships passenger manifest. It's estimated a few million did return to Europe.
Back before 1965 an immigrant had to take personal responsibility for themselves. Immigration laws from 1945 to 1965 were strictly enforced and an immigrant couldn't receive any form of welfare be it federal, state or county for the first ten years being in America. Today 50% of all legal immigrants and illegal aliens are receiving at least one form of government assistance. Yes it's a violation of the law but nobody is enforcing our immigration laws.
Today when an immigrant can't make it in America there's no reason to return home, the government (taxpayers) will step in and take care of them.
During the 1800's and to the middle 1900's there were private immigrant societies set up to help immigrants who were having a hard time and also the churches but the government wasn't in the welfare business back then because the Constitution doesn't mention it.
Bank of America was originally named the Bank of Italy. A bank established for Italian immigrants.
