Don't forget the for-profit college admissions "counsellors" who charge families for telling them about freely-available financial aid and free testing prep resources that mid/upper-mid class families learn about from their school guidance counselors. It's so bad that our guidance counselors are in a race every year to get to our students' families before the scam counselors out there do. They target first-time college aspirants, try to sell them on unaffordable college loans, charge them for worthless "advice".

Not that there aren't good ones out there, but we've encountered an awful lot of slimy ones.
