Employers who fail to confirm the legal status of employees should spend time in prison, IMO.
You know, such an incentive is a pretty darned good idea. At the very least, penalties should include IMMEDIATE cut-off of all government funding, INCLUDING emergency funding, as with the post 9-11 Airline bailout, with stiff fines on top of it. A federal regulation like that IS an incentive....airlines...no...ANYTHING which falls under the pervue of the FAA OR DEPARTMENT of Transportation should be included in this....you hire people in these national security sensitive industries without proper checks of documentation, you get shut down. You do it right, and you DON'T get shut down.
