That's a good argument for gutting welfare (then they must work to survive), but not necessarily for hiring illegal aliens or having guest workers undercutting American wages.
I am completely for bringing illegal entry into this country back under control - but that's not what I am discussing here.
If you completely eliminated illegals from the picture, the minimum wage is still the minimum wage and you are not going to get min-wage jobs to pay $12-$15/hour just to provide Americans jobs who are not willing to work for $7/hour.
If you LEGISLATE $15/hour, costs will go up to equalize that burden and then you will need $23/hour and the cycle begins again.
So what do businesses do when they can't get 15,000 hand laborers to come to where the crops are ready for harvest or new developments are being constructed or neighborhoods need work? Again, I'm not justifying anything, I'd like to hear some real solutions and not suppositions where Americans will supposedly do any job and that businesses should just suck it up and pay $25/hour for hand labor jobs.
