Many US State Colleges were supported by tax dollars and in the 90s, tax cuts started happening and funding for public colleges declined and fees started being added.
When I went to College, it was extremely cheep, books cost more than my tuition and fees. The state where I was had huge discounts for residents and since the college was in the City I was born and grew up in, I got even more discounts.
Now, kids need to take out big loans for higher education.
I will not go into cuts to public schools, these days, if parents can afford it, they send their kids to private school. When I was in school, the public schools were great, but they started to go down hill not long after I graduated High School.
