Not statistically it isn't. I invite you to cite data. Again, you can't get a bank to write you loans of that size without collateral of some kind. Banks will write loans for the subsidized amount (currently capped at $31k per student federally), plus some from other guarantee sources like state programs, and throw in a little on the expectation of future salary. The only people getting $100k loan balances as undergraduates are people whose parents are co-signing (or who otherwise have something that looks like collateral to a bank).

Note that's not true of post-graduate schools. In particular banks are willing to tolerate a much higher debt load for med school students. But the discussion here is about "Does Stanford require more debt than other schools". And it does not.
