Without some coercion, the only one thing can "rein in tuition" is demand - it would happen if significant numbers of college age people would say "the offered product is too expensive for what it gives me, I'm not going to buy".
That's not happening, college enrollment is not dropping like a rock, and the students (or their parents) are willing to suffer the cost increase. So it's their choice - with a dash of tragedy of commons, as it's probably really not worth for a tiny minority to 'defect' from college as a social concept unless a large critical mass does that.
