Apparently no one in this thread or in that article went to a real business school. I won't disagree with the idea that 90% of people in any college are complete fucking retards, but if you go to a program anywhere in the top 10, you will get your butt hole pounded on a regular basis. Most of what they teach you is how to deal with other people who you hate, by forcing you to deliver 100 page projects full of math while relying on and managing your group members.
Any legit school is going to have people from industry teach most of the classes. Sure you're going to have foreign grad students teach technical labs because no one else remembers the math. Hell some of the people in the entrepreneurship program where millionaires. There were virtually no friday classes, at least at the upper level, because almost all the professors did consulting on personal projects on the weekend.
A lot of the curriculum is designed to prep you for the corporate world, how to each shit sandwiches, etc. but if you're looking to make money on your own you go through an entrepreneurship program, probably with a minor in finance, not a general business degree or marketing major. In my school virtually everyone got jobs and that was at the worst of the internet crash, and they averaged higher salaries than the rest of the school.
Even shitty schools with low workloads can have their place. If you are starting a business while in business school (which fucking everyone should do) you don't have time to go to study 40 hours per week. Your professors become advisers more than anything else. Hell I had 2 professors give me an entire office to start a dotcom for a summer. When we couldn't figure shit out they'd tell us what to do next.
