Those who hire illegal aliens...
Some of the jobs are those that Americans won't take because the pay is too low. Like picking crops. So farmers fear if they can't hire illegals, they're out of business. And I can't say categorically that that's not true.
Of course, in this economy, they might find some LEGALS willing to pick their crops. There's reason behind everything and maybe this is part of the "adjustment" that's going on.
