I think there is work for which employers are unwilling or too cheap to pay for at American wages, and so they resort to breaking the law. (If the market decides that there is a shortage of those willing to dig ditches, the ONLY CONSERVATIVE response should be the free market one of having to pay more to attract those LEGALLY here to do the work)
I think there should be a recognition that anyone who knowingly hires an illegal alien should have his business confiscated under RICO, and his UnAmerican, terrorist supporting butt thrown in jail.

If you won't mind paying $6 per lb for your fresh vegetables and fruit, then your idea would be great!
Only problem, since Americans won't pay $6 per lb for their produce, then imported vegetables will continue to overtake the sales of domestic ones.
