When I first went to that college in the late 90s, it was $6k a year, including room and board. I had a full-ride scholarship (which I wasn't able to hang on to for more than 3 semesters, but that's another story), and it was going to pay $24k total for all four years. Now it's that much for 1 year.
By the way, if tuition followed inflation AT ALL (i.e. I checked an inflation calculator), the cost would have only increased to $9k a year, including room and board. Clearly the price tag of college has just increased out of control for the past 20 years.

You're right about the community college. That is absolutely a way to save money, but in states like PA, you'd still have to pay nearly $46k for tuition alone. That's not including housing or transportation costs. It's not as easy as "2 years at community college and then transfer to a state school" for everyone.
Go to community college for 2 years, don't take summers off, live within your means, stay at home or get roommates, work part time for your living expenses. I see people complaining about $25k per year, $100k in student loans. It's absolutely absurd.
