Absent the influx of migrants, Chicago would be closing more empty schools.
The Chicago Teachers Union has been co-opted by Marxists and their goal is to enroll as many migrant children as possible since Illinois funds its schools on a per capita basis. The most important part of the school day is the roll call. The attendance reports are used to distributed taxpayer money to public schools.
Yep, you keep those kids coming in, and you keep your job.
