I don't think that's true in aggregate, and certainly isn't true when adjusted for population size. The average doctor has far more school debt than the average dropout. Now, a pause on the first 30k of debt (or any other number under 100k) would solve that issue. 30k was chosen because that number seems to be proposed at a lot as a cutoff.
