Is the financial crisis of 2009 a business ethics scandal?

So my online course has recently handed out the project for the course. It irked me a bit that she didn't tell us more in advance and she left most of the class in bewilderment because no one knew where to find the information on the project. Eventually we found it in week four's welcoming notes, and quickly we began to discuss it on the discussion board.

Most people are choosing to write about the Enron case because it is by far the biggest and most well-known business scandal case. However, outside of that what other cases are there? I mean there are none so publicized that research is a matter of typing a word in google.

Being the rather difficult student I am I decided to enter more 'maybe' territories and argue that the financial crisis of 2009 was caused by a ethics scandal within banks. The fact that banks were giving out loans to people they knew couldn't pay them was morally wrong and because of those actions the stock market took a major hit.

What do you guys think about this topic? Green or Red light?
