There’s a saying, “the greatest trick the devil ever pulled was convincing mankind that he doesn’t exist.”
I disagree. I think the greatest trick would be to prove that you’re the good guy, and the other guy is the bad guy. If anything about the Xtian Bible is true, Lucifer is absolutely the good guy.
They can be both because the jobs they work pay too little to live on, so they need welfare to survive.
Of course that’s true for most jobs that non-immigrants work too, but a few cents more and you’re suddenly not eligible for grocery money.
