It isn't surprising that there are significantly more hobbiests here. A lot of "professionals" who have seen my Festools comments at how expensive they are. They aren't worth it, overpriced, they look like toys... etc. Its almost as if they value their time less because they do it more?
Another factor I have heard from other pros, which I have never experienced as an employee or employer, is "my guys abuse my tools." I don't baby my tools, but if I see a guy with banged up crappy tools or a guy that tosses a saw on the ground after using it, how can I expect he will do top notch work?
Currently I work alone, so I can control how my tools get treated, but when I had guys work for me I took the time to teach them.
I guess this is a bit like preaching to the choir, if you are here, you "get it."
