sorry but most MBAs I know are either unemployed or sub-employed, so I don't find them a high-salaried prone population as you do. You are living in a bubble where you can get a 100k job out of school, and being broke means not being able to change cars every year.
I'm not saying that the values he talks about are wrong, but that they are unrealistic given the constraints of economics for 99% of the population of the world.
