It isn't right, because for every kid that gets accepted because a big pile of cash helped the tutors 'come to the right decision' there's a kid who worked hard and has all the right potential who won't get that place and that's unfair.
Am reminded of the episode of the Simpsons where Mr. Burns is trying to get his stupid illegitimate son Larry into Yale:
"Well, we have a sliding scale, for example, for a score of 400 points you would need to donate a new football field, a score of 300 points would mean a new dormintory, and for Larry's score... we would require an international airport."
