Current college student here. Going to a UC like poster a bit above me. He/she already explained one really good way to go to college for cheap. There are numerous other ways. Most state schools still have a combination of reasonable tuition rates and decently comprehensive financial aid programs. If you have the money to pay, you pay full sticker price (at state schools probably a bit expensive but not terribly so). If you don't have the money to pay, the real cost of going to school is lowered greatly. I grew up in a lower-middle class household, lived and spent frugally while in college (protip #1: not all text books are necessary, #2: older editions are sufficient 99% of the time #3: the internet has lots of free stuff if you know where to look, #4: don't buy shit you don't need), took college courses in high school to get college units, and I will be graduating at the end of this academic year as a third year. I will graduate with minimal debt. This would of likely been zero debt if I didn't choose to study abroad for a semester, but I think it's worth 50 bucks a month for 10 years. Of course, this was with very significant parental help, but even so, all things considered my family and I did not pay much for me to go to school.
UC schools have been under enormous pressure with tuition hikes and budget cuts, so it is likely that other state schools would have been even cheaper. Additionally, there are numerous private schools that are more than happy to compensate a talented student with scholarship funds in order to boost its admissions profile. Furthermore, there are numerous private schools that cover 100% of financial need, although these are generally the very selective ones. The point is, it is still very possible to go to college for cheap. You do have many more options, of course, if you have an impressive application.
The information on these cheap roads to college is easily obtainable on the internet. I am of the school of thought that anyone paying $200,000 for a bachelor's degree out of pocket is a bit misguided. Further, anyone going into $200,000 in DEBT for a bachelor's degree is a damned fool.
And don't give me this "young teenager" BS, 18 is plenty old to do some google searches and figure out your best option. It is these very misguided people who are fueling the ever rising tuition hikes. It's simple supply and demand. Tuition prices continue to go up at a rate vastly greater than the rate of inflation. And yet, demand to go to these schools keeps going up along with it. We have UPWARD sloping demand! Something is wrong. The most expensive colleges continue to get more and more selective. Of course they keep increasing prices, their customers don't seem to CARE about the price! It's only good business sense. And after all, higher education is big business.
