We are still at the early stages of the collapse of the housing bubble, but it�s not too early to start pointing fingers. This isn�t a question of vengeance, the issue is accountability. If the dishwasher breaks the dishes, she gets fired. If the custodian doesn�t clean the toilet, he gets fired.
Economists think it�s very important that people who don�t do their job adequately face serious sanctions, including job loss. This provides the necessary incentive for people to do their job effectively, and sustains the economy�s productivity. This is why it is important to identify the people who did not do their job, and therefore contributed to the growth of a dangerous housing bubble.
