What is considered "middle class" on CC?

^ Huh? That’s the reality of most schools in the country. Some kids will comfortably afford the most expensive schools’ full tuition, while most will struggle to afford their state school. Same with CC.
In terms of college, if you need a number, obviously the size of the family matters.
A 2 person household with a 120k/year income is going to have a much easier time paying full-tuition than a 5 person household with a 200k/year income.
