This, it should be noted, is the very same Economist that predicted a couple of years back that 47% of jobs would go poof in 20 years. If the jobs go away and never come back due to technological disruption, since when is loading us up with a ton of new people to educate and feed a good thing? Our own birthrate has plunged because young women have had quite a job on their hands just trying to get enough stability to consider having kids and this is going to make it worse!
They will come in and live 2-4 families in one house. Fifteen of them will work and some menial job while the other 5 take care of the kids. Doesn’t cost much for each family. Get all their food on EBT and other benefits such as emergency room care. Most of them never learn English and have no intention of moving out of their old country ways and culture. You end up with another country within this country.
