I don’t see what low-skilled adult immigrants have to do with a requirement that our educational systems absorb their kids in a manner which requires resources be deferred to teaching them to speak English, which even the poorest most neglected American kids can at least do when they show up at kindergarten. Jamal might not know his colors and maybe nobody ever read him a book, but at least he knows what order he is defying when the teacher yells at him to behave and he refuses.
We came really close to relocating to a wealthy ME country for my work a few years back, and it’s a place I spent a lot of time. 85% of the residents of this country are on work visas and the 15% who are citizens are spoiled beyond belief. Anyway not only do their public schools not teach in other languages (they teach languages, as is proper to educate kids on other languages, but they don’t teach IN other languages), only kids of citizens are allowed to attend. Everyone else has to go to private school. So, while my kid would’ve been attending a very nice American or British school which companies pay for, the regular Indian IT workers send their kids to Indian school which cost much less but I believe most negotiate some tuition coverage as part of their contracts. French, Australian, etc, all had their own. The absolute lowest level workers ie Pakistani and Bangladeshi laborers and such do not bring their kids, because they’re living in work camps outside the city.
Of course, they also don’t allow certain people in. A married foreign male with a work visa can bring his wife and minor children. Once male children turn 18 they have to get their own work visa or go home. A married foreign female with a work visa cannot bring her husband unless he also has one, with exceptions for certain jobs (women with exec positions, doctors, engineers, a few others. I am middle management in engineering so mine didn’t need one, but my company was going to give him one anyway just to keep things cleaner). So, they successfully ensure there is no chance for a bunch of irritable pointless men with no jobs and no ability to get them wandering around causing trouble.
