For some context: according to US News, the most expensive college in the United States (among schools it ranks) with respect to tuition (and fees) is Columbia at ~$55k/year. Below that, there are many schools in the $52--53k/year range.
If you consider the total cost of attendance including room, board, books, and other costs, the estimates for the most expensive schools peak either at $68--72k/year at Columbia or ~$70k/year at Harvey Mudd, followed by at least 40 other schools over $65k/year.
The most expensive in-state tuition at a public college is $16--17k/year. The most expensive (in-state) total cost of attendance are a few schools (like NJIT, William&Mary, and some UC campuses) in the $30--34k/year range.
Raw numbers are pretty meaningless in this context, I would say. If that was the cost but there was a zero interest, flexible payback load from the govt available to everyone, I would still count them as having access, for example.
