There's no comparison, just like there's no reason to be as ignorant of the facts (as you are) requiring LEGAL immigration when our ancestors came!
They were examined and if found to have a communicable disease, they were quarantined until pronounced healthy. And they needed to have an American citizen sponsor them and guarantee that the immigrant would not be a burden to the state. They got no welfare, no free food, no free smartphone, no cash stipend, no free housing, and no free transportation to any city they wanted, and their education was IN ENGLISH, so they were required to learn it. And if they broke the law here, they'd be just as quickly deported and not set free to continue their criminal behavior.
So please, educate your stupid self before making such ridiculous comparisons in the future!
