An MBA is not a magic wand, but it's a good advantage in today's business world. I was an engineer earning peanuts previously, did an MBA 2 years after work at 27 years old, and now working in the finance industry earning a multiple of my previous salary. The important thing to note is when you do your MBA, if you do it when you're 30 to 40, you're probably too old to maximize the advantage of an MBA. The average starting salary of an MBA is about USD 100k, so the lower your pre-MBA the more advantageous it is! If you have a high starting salary and you do an MBA, you're probably short-changing yourself in the end due to opportunity costs and a marginal increase to your pre-MBA salary.
