I would support government intervention to help level the playing field if the disparity was large enough. I don't regard disparity as a problem in itself, however, in this particular case, it would serve as a likely indicator that individuals are being greatly held back by their economic background. I'm aware, it's hard to ascertain whether such a disparity is caused by lack of opportunity as opposed to lack of desire on a the part of an individual, however university places are something people even many poor people strive hard to attain. A group such as "tall people" being overrepresented would be different, as the level of causation would clearly be lower than for rich people, if active at all, although I wouldn't think that if the Uni student body was 100% comprised of "tall people".
