We don’t “know everything by heart,” just know what we do know.
I believe @circuitrider was referring to, “A college can be need-aware and still offer more generous financial aid packages than some need-blind colleges.” We DO see that. Not suggesting you read thousands of posts.
Imo, no, endowment size does not directly correlate with generosity of financial aid, except in theory. A high need kid, per that college’s policy and formula, will likely receive more than a kid who needs less, per their formulas. Is that “generous” to the latter? Maybe. But not necessarily.
Harvard allows for a higher income level than others. But whether you get the most from X or Y depends on those policies, not the size of the endowment.
If you’re trying to figure your shot at good aid, run the NPCs, if you aren’t a biz owner and the parents are together. Resources like Financial Aid or Dummies will help.
