Supposedly they're here to do work the natives don't want to do. Aside from the obvious bullshit....ie the natives used to do those jobs and if you paid them a market wage I'm sure they'd still be willing to do those jobs......and they're supposedly here to shore up the pension schemes in various western countries which are aging because the birth rate collapsed.
OK.
So why should they be allowed to receive public assistance? I thought they were supposed to be here for our benefit....ie to contribute to society. How does adding a whole bunch of leeches to the welfare rolls help shore up the pension scheme? They're not working. They're not contributing anything. What's the benefit to us of having them here? There is no other reason for them to be here at all.
