I have said on here several times that I find the whole DB v. DC thing pretty far inside baseball to make much of a difference for most people on the street. Each have their relative merits, each kind of regresses to the same returns and benefits paid for the exact same investments in the long-term, and it is more important that you have something there for you than it is one particular pension configuration versus the other one.
I was speaking more about the outward appearance of the superiority of a DB plan compared to a DC plan for the man or woman on the street. People are risk-adverse, and a DB plan appears to (outwardly) to remove a significant amount of risk and exposure to the market. Of course, that is nonsense -- both types' eventual payments are functions of returns, but I think you know that. A DB sounds nice, but most people are not going to adjust for the long-term risk that promised benefits will need to adjust to market returns.
Which... is what DC plan does. The math wins in the end.
You say all those things about education, but I do not think I have yet to find a career that does not come with its own set of gripes. I cannot count the number of times I have heard, "If I could go back and do it all over again, I would go into finance/education/medicine/law next time around," and very often one person telling me their field is not all it is cracked up to be is telling me they want into the field the last person said they regretted.
I know teachers work hard, but there is not a career worth having where you do not have to work hard. Having three months off each year, though, is pretty nice.
I feel sorry you have to play game warden, though. One of my best friends from graduate school was an ex-high school history teacher. He said the kids were great, but if that he had to take one more phone call from an irate parent in small town northeast Iowa about how giving little Susie or Johnny a C+ was going to keep them from getting into Harvard, he was going to jump in front of a train. He sells insurance now.
