The immigrants are like the slaves, they came here to work for us.
The only difference is that the slaves didn't come willingly.
But in both cases, they are here because they were invited, and they were welcome as long as it was financially beneficial for us for them to be here.
They're all here because we're too lazy to pick our own cotton, or too cheap to pay our own brothers to do it. We have no one to blame but ourselves.
