Business School Problems

Think there is trouble with business schools, they just discovered design and think its something revolutionary. Tom Peters is in Toronto today making a presentation and has a set of ppt slides with a quote from Jeffrey Pfeffer:

"There is little evidence that mastery of the knowledge acquired in business schools enhances people'’s careers, or that even attaining the MBA credential itself has much effect on graduates’ salaries or career attainment."

How about this, why don't companies start hiring people with brains not degrees.
