I make a little more with a MS than I would have with my BS, but not enough to justify the 2+ years of lost earnings while I was in grad school. I am in engineering BTW.
ETA: I went to grad school because I hated the job I got in 2003 right out of undergrad, and the economy was terrible for engineering jobs. I now have a job I like and make about 3X what I made in 2003. So I have no regrets.
