Quote from torque:
Possible that the markets will improve, but I personally doubt it. I think what we're witnessing goes way beyond cyclical changes. We shall see though.
Also it's not just the money. Even if I were making $500K/year in my current job I would still leave for a top business school precisely because I want to do something else, meet really interesting people, and acquire a strong network.
So you're likely in your mid 20's and you personally believe that market forces have changed permanently? Ok.... you realize how naive that sounds, right?
You didn't answer my question: Are you a leader? Do your coworkers respect you? Can you organize people and succeed in accomplishing complex tasks? Are you well-spoken and charismatic?
Be honest. If you're not a leader its fine, most people are not. There are plenty of well-paying, intellectually satisfying, fun careers that don't need an MBA.
