Coming over here and working for nothing. Fornicating with their white masters and having mixed-race children slaves. Putting non-slaves out of jobs.
But the next-sorriest by far were Indians running around in jock-straps, refusing to work and claiming they had some prior claim to the land regular people wanted. Even though those Indians weren’t even citizens.
The third sorriest were regular people who didn’t come from rich wealthy families, didn’t own anything, and were forever pestering mine owners, factory owners, railroad owners, and anyone else hiring them to pay them a living wage. They couldn’t even be trusted enough to have a direct voice in the proceedings of government. Everyone who did have a direct voice could see with one eye those regular people would all the time be taking away their power and wealth and property rights. Given half a chance.
Luckily there were rich wealthy people who knew from telling their servants and slaves what to do and the servants not doing it right, that regular people were crap. And when those rich wealthy people were setting things up they made damned sure those slaves, Indians and regular people wouldn’t get their hands into the pockets of the decent rich wealthy people running things.
But slaves were far and away the worst of the lot. Came over here, half of them illegally after it was already against the law to import slaves. Putting regular, honest, hard working regular people out of work.
