Born to fish, you said;
"Obviously there are a lot of folks on this board that feel school teachers and government employees are a bunch of overpaid whinners."
That's kind of funny because now, a lot of us "know" who some of those overpaid whinners are!

But getting back to your question;
"If they have it so easy, why don't you apply for these positions you're complaining about?"
Here's just a few of the reasons for starters why many people do not want to work in those public positions.
Cronyism and nepotism, it runs ramped in many state jobs! You know it, so I will not go any further on those two. Next, people know that they will never be promoted on their abilities of there skills, or how well they do their job. When you work as a public savant, promotion comes with time and not with how successful you have perform your job. In free enterprise, you get paid for what you are worth and not for how long you have been there!
In yes, some people actually do enjoy doing physical work and don't feel dirty about doing it. That is sometimes hard to find in a lot of "public jobs" People dream about owning and running their own companies and business in private enterprise, while people in public services often have nightmares about being number one!
Well take no personal offence BTF, because we already know that you are not one of those "many"! We know that you have a small business on the side, so that tells us that you have ambition. But I am sure that there are lots of "other reasons" why people choose not to work in public positions. These are just a few quick ones that have come to mind to answer your question.
