Colleges also have the ability to deny or accept students based on standards that they set themselves. Are you saying that elementary and high schools should be allowed to deny entry to students that they think will hurt their bottom line? Should they offer scholarships only to those students who will bump up their graduation rate and test scores to make their school brand better? Maybe we should let our high schools offer scholarships to students who are great athletes so that their sports teams will become well known- also bettering the brand. Someone has to be willing to take in and teach the lower-performing students who don't help the school's image. If Ivy league schools were forced to open their doors to any family with a voucher- regardless of academic ability or socioeconomic status, then I'd be in favor of that system.
