I think that whole problem of subprime crisis is a bit more complicated than two sided coin but most important thing in this problem is education and system of education. Trying to find a person or institution who is guilty is always subject for debate but there is no doubt about importance of prevention. My opinion is that part of the education on the schools should be economy "for dummies"
The things like interest rate, lending, borrowing and saving is the biggest issue. I read an article about Financial Literacy of middle class and there was huge research based on survey where 93% of people were not able to pick cheapest mortgage offer out of three examples. This is not a mistake of brokerage firms or their clients. This is problem of the system.

Basic education on the schools is boring. I know that. but there is a plenty of options how to educate young people by playing a games Lets call it gamification of the education. For adults is even better if they have some basic knowledge.

There is plenty of movies which are perfect material for education. Some of them are nice example how to educate young people in our schools. Just try to imagine how they will react once they see that theory they have learned is worthy. Playing games and watching movies is not boring. They can imagine what they will do with situations as their famous actors. I think this can works.
