Because in practice, parents of sufficient wealth usually do contribute towards 18 year olds' education (or their living costs where the education is government funded), and every subsidy a university gives to a multimillionaire's offspring means less subsidy available for the genuinely poor.
Funny, that missed me. I FAFSA'd out of support due to my parents income and didn't get a dime from my parents. I suppose they supported me with the clothes on my back, but that is about it. I'm pretty sure I sit with a majority of my generation, and I find the only people placating this abusive pillaging to be those who simply do not perceive it is happening. In practice sufficient wealth to contribute doesn't mean the motivation nor incentive. I truly hope this corrects itself in time, but it is far far too late for me. If I achieve moderate financial success I'd most likely philanthropize in the form of a scholarship dedicated to exactly this gap, and/or lobby for change.
