In the end college costs so much because people are willing to pay, because they think it's a good investment. Generally they have been right, college was the best investment you could possibly make historically. Now it's just an average investment, but the FOMO of not going puts it over the top.
We are questioning if it is even an average investment, especially the truly high-cost and selective private schools where tuition sits at $80,000+ contrasted with $30,000 at our state's well-known and respected flagship university. The extra $200,000 in costs is breathtaking to consider.
