I've never heard of a salaried employee that works for an AV company owner. I know several people who own their own biz. For a bigger job, they'll hire a friend who needs some cash to help out. It's all commissions it seems like.
Tough economy makes this field very difficult right now, although I know you can say the same for nearly anything. Talking with one owner, he says even the little things. Example: people are just using TV pedestals instead of paying someone to wall mount it and run cabling, for instance.
