No doubt there is a range, but I am not going to repeatedly post
@wllm -esque eye charts every time I want to point out the high costs.
I agree smart students can get a real deal. My S-I-L took full advantage of cost arbitrage and still landed a BigTen degree. As for mean vs median, I doubt a big change. The big differences are in-state vs. out-of-state vs private. But then colleges don't encourage poetry majors to go in-state and doctors to go Ivy league so the issue of over-priced degrees remain.
