Maybe I disagree a bit here. They'll be dead. When the collapse happens, and the illegals try taking stuff from citizens, it's no more Mr. Nice Guy as those citizens fight back. Mamas will kill to defend their kid's needs. We just don't know how the "authorities" will cope with it all, a big unknown.
But I agree with the mama defending comment ☺. Btw. Bottom line we're bleeding from wounds in every sector. We need to try to stop it soon or we bleed out. Real leadership is critically needed. And avoiding a mad max thing is very preferable. I've seen it. No one sane wants to go there.
