On the one hand, that's a selected group of people who sit at desks and can chat on a web forum during the day at their jobs (as I am right now), so I wouldn't take them as representative.

On the other hand, the trades fucking suck - there are posters here who I will generously interpret as being a bit... touched perhaps? when it comes to the realities of work and particularly pay that the average tradesman must face. I'm sure somewhere, some tradesperson in the world is making a couple hundred thousand a year, but statistically speaking, basically none of them are. There's a reason they want their kids to go into a different line of work.
