Sure, someone else certainly does want that seat, provided your school doesn’t suck so much that there’s empty seats, but that doesn’t mean they deserve that seat. Presumably entry to college is awarded based on merit, and success or failure in college should also be based on merit. If I choose to screw up that chance, then that’s on me, and it’s probably better that I learn that lesson early in life (i.e. in college) instead of teachers enforcing rigid structure to increase graduation rates.
