FWIW: That (bagging Fed Student Loans in their aid packages) is basically meaningless.
Dartmouth provides full scholarships to basically every student who doesn't come from a wealthy family. That is about $70-80.000 per year - so having a couple thousand guised as "Fed Student Loans" (as opposed to 100% University scholarship) is rather a non-issue.
Those who do come from wealthy families (maybe 40% or so of their 5,000-ish student body) certainly don't need to take Fed Student Loans (which wouldn't amount to more than rounding error of the sticker price for Dartmouth tuition)
As to Dartmouth's endowment value - about the same as PSU (maybe a tad higher). Of course, it is a MUCH smaller school - and they spend a hell of a lot more of the endowment per year (in both real and relative terms - about 3 times as much $ for $) on scholarships and grants. They also typically earn significantly higher investment returns (11% higher than PSU just last year - amounting to the better part of $1 billion of "free money" just by managing their assets better than PSU manages their's).
Just another reminder of the stunning costs involved in Penn State's fiscal mismanagement, for the people who care about such things (added that specifically for Bob - so as not to disappoint him
)
