How Expensive Is School?

So to really real in the new school year, let's talk about school! This year's important for me--I'm now a freshman--so I've really been thinking about my future recently. Especially the costs. A good living is going to cost you, and not just money. Time, effort, energy, etc. It takes more than just a few bills to establish a comfortable life.
But, of course, today we will only be talking about the dollar aspects of this. How expensive is school money-wise?
Well, basic education isn't all too bad excluding field trips, dances, and other extra curriculums. Elementary/primary school is only about $20-$35 per student. Secondary/middle is about $30-$50. Middle and high school varies a lot, especially in America. Depending on how you go through high school, you could end up paying up to a thousand dollars. Though, it's easy to keep it under $300. Most of that money is going to college credit courses, larger tests you have to pay for, certain classes, etc. High school gets busy.
For college however, prices hike way up. The average for attending an in-state college is about $9,000 dollars, to attend the same college but out of state is about $21,000. And private colleges, on average, are about $35,000.
Even at that, prices are clearly still rising. Which is an issue. In for years, I don't wanna be stuck dropping 50k on something as basic as a bachelor's degree.
