Being an MBA and having spent a lot of time with a large cohort of the same, the "Entitlement," "Misguided Thinking,"and "Selection Bias" critiques sound a lot more like the caricature that's made of MBAs by non-MBAs (or self-loathing MBAs trying to impress non-MBAs) than the vast majority of real people who have the degree. If this represents the majority of the MBAs you've met, then I fear you have an unrepresentative sample. We had those folks, for sure. But they were the dorks and the minority.
