MBAs are worth shit nowadays. They're relics of the 80s. It's now almost 2012. It's a lot more lucrative to learn how to write a smart phone app. It only takes a week or so to master. You don't even need to know how to write code anymore. Compilers do that for you. eg

I have 4 on the app store at the moment. The first 3 have bombed because I didn't structure them the right way. The latest one I've had some success with. I doubt if it will make me a millionare but it's definitely getting me a better ROI than some stupid MBA ever would.
An exception would be an Ivy League MBA but you actually have to work very hard in order to get one of those.
