Earlier quoted context omitted.
You don't need an MBA to solve those problems. It's a problem with prioritization, not lack of ability.
That's exactly what an MBA does. Teaches you to prioritize effectively. It also gives you countless examples of businesses who don't, and the consequences they suffer. Sometimes learning these lessons in the real world can be very costly.
The two primary motivations for getting an MBA are completely unrelated to obtaining an "education":
1. Career transformation (i.e. you're a marketer that wants to go into banking.. basically impossible to get interviews without going to bschool)
2. Obtain a professional network
"Learning" is really a tertiary priority.
