Actually, I do. It works like this. Many illegals have fraudulent SSNs. That means, they pay taxes -which is more than I can say for many US citizens. They are paying into a system they will receive no benefit from.
Because of the wonderful freedoms that citizens of the US enjoy, thanks in part to our constitution and the laws built around it, employers are asked, but not required, to have employees show their citizenship. But, many of the totalitarian lovers are wanting to change that for “security.” Hmmm…sacrifice freedoms for security…that is not a good thing.
