When I click that link, I get redirected to https://www.brookings.edu/articles/no-aid-to-religion-charit.... The article is titled "No Aid to Religion?: Charitable Choice and the First Amendment". I read it, but it was written in 1999 and not relevant. I'm not sure what's going on there.

I did manage to find the article though. Thanks for sharing. Based on my own experience attending a private university, I had thought students at ivy league schools mostly used private loans. Unfortunately, the article doesn't break out which debt is government-backed and which isn't. This much debt in general is problematic for young professionals, but my understanding is that "cancel student loans" is about the government-backed debt. I'll have to see if I can find a breakdown somewhere.
