That's what all of this push to make kids "college and career ready" is all about. Many kids do not have the capability or the desire to do college-level work, and this guarantees these kids will end up dropping out and be forced to do low-wage work.
Even those who CAN do the work and go on to college will find out that upon graduation, they can't find jobs in their field. They will be dumped into the low-wage jobs, if they can find them at all, and drive the pay down even further.
It's a win-win for the privatizers.
