More immigration madness from Arizona!
Of course, if anybody wants to stop illegal immigration, it'd be easy: just raise the minimum wage exorbitantly for illegal immigrants. That would punish the employers who hire them sufficiently so they won't be hired. Then, when such workers get hired under the table anyway, enforce it when employees come to the authorities and demand their pay. Illegal immigrants would be doing the policing for the government. The jobs would dry up, and the problem would be negligible.
Of course, concern about illegal immigration isn't rooted in common sense or concern for American workers, no matter what anyone claims. The root cause is racism, jingoism, xenophobia, ignorance, and stupidity.
