What amount of pay is going to motivate a lard-assed welfare parasite to go out and pick grapes?
Ping.
If that price is too high, and the government won't reduce welfare benefits then automate the process.
If labor costs are too high, then employ labor saving capital, aka machines.
I don't know what amount of pay it would take, but hunger would be a real good motivator. Plus I see people paying for groceries all the time with food stamps. They often have hair extensions, fancy manicures, bling, and drive off in very nice, late-model vehicles. What if we cut off their benefits so they could no longer buy all that stuff? They'd darn well work.
Hey these illegals aren't picking grapes anymore. They are taking construction jobs. Framing, roofing, plumbing and yes even electrical. They are doing it for far less than an American worker can afford to do it for. They will live three families to a home to accomplish this. They are taking what once used to be good paying American jobs and converting them to wages fit for the parasites that are coming up and taking them. How does an honest contractor compete with the bastard who hires these illegal immigrants. Work hard and cheap with muscles flexin or you'll be replaced by an illegal Mezican.
