Hah.  I remember when  I was in my early 20s and thought the same thing about those that I worked with, but the weird thing is they got a lot smarter as time went on.  So you'll be either the upwardly mobile guy that everyone talks about behind your back, or you'll be the know-it-all who really doesn't know-it-all.
The fact that you post on a message board tells me you are the latter, which isn't a bad thing, and you'll be in the group you loathe in another ten years or so.
		
		
	 
It really bothers me when people assume they know something they obviously don't know. Your post is a good example of this. Assuming that there are these two specific groups of people in a bodyshop?  funny.....You last worked in one when?
I was talking about people who have been fixing CARS LIKE YOURS for 30 years and couldn't weld bubblegum to more bubblegum. I am talking about people who take a torch to high strength steels when they have no idea of the makeup of the steel involved, and are too ignorant to know that they just reduced steel that is made specifically for a certain purpose, to the type of steel they have EXPERIENCE with. Which is mild steel and most definitely not the best choice for the safety of your vehicle. 
Just so you know, in an accident you might die if your vehicle was repaired improperly. The bad thing is that 99.99 percent of the time nobody will know that you might have lived if it had been done right, because your car is supposed to be smashed when you wreck it. They don't send out someone like the FAA to see why YOU died, regular accidents aren't that important. 
It may be a little known fact to the real world but unless we are talking a simple bumper job on a new car we are ACTUALLY talking about something that can put your life in danger if you don't have it fixed properly. 
I am 34 and I am the guy the boss gives the jobs to when he wants to make sure they are done right. 
I am the guy he sends to class to make sure that someone in the shop knows about current vehicles and proper repair procedures. 
I guess I was a bit naive about posting on a message board. I thought it was something I do for fun. My bad. 
The good part is that I can now assume that most other people are like you said, the know it all who doesn't really know it all. Kinda funny how neither one of us must know it all.
