What you get out of an M.B.A. programme, no matter how much experience, is functional tools and understanding in disciplines: you'll understand economics, you'll understand marketing, finance, accounting. That, M.B.A. programmes do very well.

What protectionism teaches us, is to do to ourselves in time of peace what enemies seek to do to us in time of war.

Often, M.B.A.s will parachute around from one company or industry to another, without really understanding what's behind it.

If you're functional, it doesn't matter if you're mad.

What I have against M.B.A.s is the assumption that you come out of a two-year program probably never having been a manager - at least for full-time younger people M.B.A. programs - and assume you are ready to manage.

I describe management as arts, crafts and science. It is a practice that draws on arts, craft and science and there is a lot of craft - meaning experience - there is a certain amount of craft meaning insight, creativity and vision, and there is the use of science, technique or analysis.
