A bit of a tangent, but whenever I hear people complaining about greedy professors scamming students into buying their books I think about how much more money many of these highly educated people (particularly STEM people) could be making if they chose not to teach. Most people didn't become professors for the money.

No, it's not good if educators price students out of education, no it's not simple to find funding for education, but we shouldn't expect our educators to be martyrs and then bemoan our declining global education rankings.
