[Team Fortress 2] How have half these guys kept their jobs?

I'll admit, a good number of the mercs can have their places on the team justified by either uniqueness or demeanor: Engineer is an unparalleled multi-disciplinary scientist, Medic's skilled enough to literally resurrect the dead, and  Sniper, Heavy, and Spy are all professional (if quirky) and don't usually go out to cause problems.

But look at the rest of the team: Scout is brainless and illiterate, Demoman is a raging alcoholic even when he's on duty (and even worse when he's off), Pyro is a violent schizophrenic who's not above attacking his teammates, and Soldier randomly assaults people in public with lethal force (if his penchant for neck snaps is any indication). How have these guys not gotten themselves canned with their antics?

Because they get results.  

The Scout hurts people like grass grows, birds fly, and the sun shines.  He excels at quickly getting to the people who need to be hurt, and then hurting them.  

The Demoman's a good demoman because if he were a bad demoman, he wouldn't be sitting here talking about it.  

The Pyro is insane, yes, but it's hard to argue he's not effective at burning people.  Sometimes you just need people burnt.  

And yes, the Soldier is also insane, but he is also deeply knowledgeable about the history of warfare as well as the origins of zoos.  Well, he believes he is, anyway.  Point is, sometimes you need the kind of guy on your side who will go on a Nazi killing spree all the way to 1949.
