Discussing money is just bad etiquette, and more importantly, nobody's business (unless it's in negotiations with the person paying the salary.) Sometimes it's downright funny to talk about what one makes on a particular gig, like me hosting a jam for $10. But real salaries are best kept discreet in public places like this.
There are a few reasons.
Salaries in entertainment vary widely. One person's salary for a job has little bearing on what another person doing the same job for someone else would make. So there's an accuracy factor at stake when talking about what one person makes. There's no 'scale' for traveling techs. While there's union scale for players, it's not very much money, varies by the particular local, and there just aren't many union dates anyway. So the info may be accurate for L.A. members, but it doesn't necessarily apply elsewhere. I could quote L.A. Local 47's rates, but it really wouldn't be helpful if you're doing a union date in Colorado Springs, for example.
And, people's perceptions of what musicians and techs make also varies, and is very subjective. If I divulged what I make on the road, the responses would range from "that little?" to "that much?" In other words, while the info might be interesting, it would be useless in terms of guaging what a musician might make with a given artist.
Obviously, salaries will also vary depending on the revenue generated by the artist, and how generous they are with their payroll. It's completely subjective, there are no rules, standards, or guidelines. The person paying makes up a number, and the person applying can say yes, or no.
A few musicians don't seem to mind telling what they make, I guess that's their call. Same with some people in regular jobs. But I bristle a bit when I hear someone say what they make. I mean, minimum wage gigs are one thing, we all know the range for most hourly wages. But above a certain level, it's just not a topic for discussion, whether in a forum, or in person.
