You got the order reversed. The network is first, or perhaps more accurately, first, second, and third. You mix that with soft skills, and basics of business (accounting, strategy, marketing, etc.), sure, but the most most most important thing is being able to network and get good jobs.
Also, as much as you want to rail about MBAs, it's not the MBA that turns people into mindless capitalists. That just the society we're in. Some MBA folks came in greedy as fuck, some do their job mostly against their will, but they're all playing the game because they have to, to earn a living. The network a good MBA gives you helps you make it to the top, and so MBAs are over-represented in the ranks of the top 5%, but there's plenty of folks that are as greedy and would go as far as any MBA to make money, they just don't have the background to get them there.
