> And if you look at any graph of college costs vs wages over the past 40 years or so, they have simply skyrocketed.

Absolutely, no debate there. The particular surprising claim in question though was about whether they have declined in the past couple of years, relative to a peak in late 2010s. And there, measured either in CPI adjusted costs, or relative to real median wages, they have.

But of course, the drops are small, and it's only been about 1-2 years. I'm not sure this really indicates a sustained trend, or just the fact that college cost increases have (for once) lagged inflation over those 1-2 years.
