I knew I was covering my college tuition and even in 2000, I couldn't understand how I could ever afford out of state tuition and room and board. I had near perfect grades and solid test scores, but the financial obligation scared the hell out of me and I had no idea private schools handed out big scholarships for good students.
I ended up staying in town and going to my local state college and had a good experience, but I completely missed out on the prospect of going to a top university where I would meet other ambitious and curious people. I worked part-time to full-time for four years to pay for my tuition, and it was tough. I wish I could've been immersed in college and academia and even college-life, but the cost just felt like a huge barrier when I was 18 years old.
TL;DR: I fear poorer people may be more afraid to attend college because of the costs, causing an even greater gap between the haves and have-nots.
