Why is this flagged?

It's a clickbait article with almost no substance. It lifts all data from https://www.aei.org/publication/more-on-my-efforts-to-advanc... and adds some lazy commentary.

This reminds me of Professor Doom's rantings like this one

"Illinois University: Cut Faculty Pay To Zero" http://professorconfess.blogspot.com/2018/05/illinois-univer...

Tuition increases are mainly due to expanding administrative staff subsidized by a bottomless supply of $120 billion+ yearly in federally guaranteed student loans. If you aren't rich (or destitute and eligible for a full ride) you're going to take a big hit.

You don't have to be destitute to get quite a lot of tuition assistance at Michigan's Ann Arbor campus:

The $11 million divided across 45,000 students is $250, so hardly the main component of the $15,000 tuition.

What I got out of the article is you can almost use the letters in diversity to spell divides.
