I don't have a dog in this hunt, but I could suppose things that could be wrong. Why not post some of the potential issues?

Were the fees too high?
Were the results over-promised?
The education is not valued by the market?
They did not offer the courses needed?
Were they simply sucking fees from indigents who could qualify for "programs?"
Did they accept people who they should have known were not able to complete the courses and succeed?
Help stop the guessing and tell us.
