That only works if the people are skilled, high earners.
Here in Illinois, we spend at least $11,000 a year to "educate" each illegal alien kid. Those guys working under the table aren't covering that with their sales taxes.
That's another reason the Chicago (and Illinois) pensions systems are in such a huge hole.
If you're expecting these guys, or their kids, to cover your Social Security checks in a few years, you're gonna be disappointed.
True, but public schools are basically employment programs for many people who are marginally employable but somehow get paid like they are professionals. If the education establishment could figure out a way to do it, they’d have 50 teachers employed in a school with no students.
