and is heavily recruited by Harvard, Yale, and Princeton, at least, being well within the scope of their financial aid initiatives.
On the other hand, encouraging people to apply with almost no chance of admitting them is not "recruiting"; it's playing a numbers game. I say "no chance of admitting" because it's nearly impossible to clear the extracurricular bar at the socioeconomic 15th percentile. At that level, the "right" extracurriculars are not offered, but you're not so poor that you can pull off an "overcoming challenges" essay (that was the admissions schtick du jour ca. 1998-2003) or that a college can brag about admitting you.

seems to have been part of changing the culture of university admission offices. A student from a family with an income at the fifteenth percentile of national household incomes is a rare student at the most selective colleges and IF the student has competitive grades and test scores and some economically reasonable extracurricular involvement, the student has a great chance of admission today and a very good chance of lavish financial aid. Colleges today do brag about admitting students at that income level.
