Point taken, but it's very common to adjust by CPI (or some other price index) when comparing prices over time.
All attempts to track prices over time have some flaw. But not adjusting for inflation in a chart that goes back ~20 years could also be perceived as misleading.
Moreover, we are starting to see growth in real median wages again. They are already above Q4 2019: https://fred.stlouisfed.org/series/LES1252881600Q. So I think it is fair to say in some sense that the real price of attendance has started to go down (albeit not that much).
