Add on-campus housing and food plan and it's another $8-15k per year on top of that for in-state, maybe more now. And that covers the two main semesters only, summer and winter sessions have their own extra costs.
yeah 100k wouldn't surprise me when it's all said and done, and either way it's not something 18-year-olds should be forced to go into debt to obtain and shouldn't be treated like it's a car purchase
