I know he is just crunching numbers for unrelated jobs and unrelated colleges and making a conclusion based on that and no real knowledge, but I know tons of people who worked through college.
A lot of them were work study program people, although on the east coast. If you Google the school he talks about, though, you can see they offer a similar program where the college pays half the student's salary:

So a work study student only costs the employer half as much, and would generally be assumed to be earning a full pay check for working half the time and studying half the time. So it seems very doable. Generally a student with such low income isn't going to be paying full price anyway, so his other number is off too.
