A master's degree in my personal experience simply denotes someone who was willing to pay an exorbitant amount of $ for 2 more years of "school time" (I'm not going to say learning) in exchange for the ability to claim a "higher" degree.
Aside from my own experience, I know many people with masters degrees. None of us can point to anything meaningfully learned in those 2 (or more) years. It's a ticket punch for cash.
Setting aside my own knowledge from inside, I have worked with *many* MBAs over the years. I've generally found them to be highly talented at presenting themselves and their ideas as brilliant, no matter how intrinsically stupid either may be. I've yet to meet an MBA that was successful, that (in my opinion) wouldn't have been just as successful without the MBA. Most MBAs I've known are merely the business equivalent of highly polished turds.
Note I'm not hashing on academics; I wouldn't say this about PhD's who have to work fairly-to-incredibly hard and demonstrate meaningful knowledge to earn that degree. I generally admire PhDs.
