The problem is the mind-set of business schools. It doesn't matter which one, ALL they teach about is making money the most money, increasing profits, etc.
There ought to be a system set-up that requires CEOs, traders, etc., to take continuing education classes just like high school teachers are forced to take.
To become a highly qualified CEO, broker/trader, one would have to take courses in ethics, etc., then as as part of their practicum experience they would : visit homeless shelters, live on the streets for a week, live with a family for a month that's going thru the eviction process, experience incarceration first hand etc... all these practical experiences will help develop their character so they won't make mistakes like AIG, etc made.
