So it goes back to the employers should be held responsible. I don't see that happening often.
You and I certainly agree on the employers part!
It's definately not happening enough. However, I thin the Real Id Act will actually help some because it gives employers a way to verify that the employee is legally in the country. It therefore removes the excuse that the employer reasonably didn't know or couldn't easily find out without possible violating our strange equal opportunity laws.
Lots of little pieces are starting to come together to help make enforcement more practical.
