If they can read a graph, have them look at this blog post (the entire site is great, but this particular piece has stuck with me):

You can enter any school to see specific data about that school. They're all pretty wild, but if you really want to make an impression, try Northeastern: in 2001, Northeastern had less than 15k applicants and a 70% acceptance rate. In 2021, there were more than 75k applicants and the admit rate was 18.4%. And of course, all the top 50 or 100 schools have become even more competitive in the past 2 years since this data was released.
