The following is an idea I think I've posted before, and no, it's only semi-serious, not totally serious.
If you want to get rid of the illegal immigrant problem OVERNIGHT, all you have to do is repeal the 13th Amendment. That's right. Bring back slavery.
So if illegals come to the USA looking for work, they'll find it. Will they EVER find it!! They will find more work than they imagined. Of course, they won't get paid for their work, but I'm sure that there are those who are quite certain that it is 100 percent better to live in the USA as a slave than to live in Mexico as a free person.
So slavery is really in the slave's best interest, you see.
And imagine the competitive advantage that slavery brings. After all, countries with big populations like China and India have de facto slaves, don't they? So with US slavery, the US can compete once again in the world market, with its supply of cheap easily replenished Spanish-speaking labor.
Capitalism and slavery go together. They always have. Slaves can't form unions, they don't put a burden on the healthcare system, they don't have any wage at all, much less a minimum wage. Besides, they get fair compensation in the form of a shelter of some kind, and maybe clothing of some form and some material that might be called food, and they don't have to worry about things like investments or retirement or education or medicine or how to spend their leisure time. They sure as hell don't have to worry about unemployment. Yep, slaves have got it made!
So why not kill two big, fat birds with one stone? Make the US competitive again and put an end to all further illegal immigration! Who could possibly be against this? When will someone from the Party of Lincoln take up the "Bring Back Slavery" banner?
