Our son has a bachelor's in info systems, is about to earn his MBA and has a great job, now and will get a raise and continue in that job when he completes this degree. Of his graduating class of MBAs, most are already employed, or have jobs lined up (and unemployment in our area is around 12 percent in our area.)
Congrats and good luck to your sons.
In the stock market, my field, I do see a big preference for advanced degrees. But I don’t see a big difference in pay for those who got the degrees and those who advanced through the ranks.
Having said that, employers also gauge people who have advanced degrees as being individuals who can stick to a plan and complete it.
