Pollyanna, meet Chicken Little!
To the latter, I say ignore prestige entirely and ask yourself which school offers you the best opportunities to learn and grow: which professors did you have better interactions with? which offers the best combination of general education and specialized majors/programs? which offers the best advising/mentoring systems? which offers the most relevant mix of extracurricular activities to your interests and goals?
To the former, I say don't wait for Congress to increase Pell Grants: start spreading your wealth to the "deserving poor"(ly endowed schools that could do an even better job educating larger numbers of the nation's working class undergraduates than you could even if you raised your percentage of students with Pell Grants to 15%). Oh, and let your graduate students and adjuncts unionize while you're at it. They're the ones who will be the strongest advocates for quality in higher education. It's for your own good.
