Are all tech support people purposely stupid and incompetent?

I mean, is it just me or does everybody end up having to write 3 or 4 emails asking the same questions before finally getting an answer.
It doesn't seem to make any difference who I deal with... it's always the same thing.
Write a long involved email explaining exactly what the problem is... only to have some doze write me back either answering a totally different question than what I asked.. or treating me like I'm a total idiot by giving me stupid, idiotic solutions that any 5th grader could have figured out for themselves.

It's like.... "yes, I've already tried that. Yes, I know you're supposed to hit that button... yes.. I have enough brains to figure all that crap out for myself before writing you for help. Why do you think I'd be writing you if I hadn't tried that already?

ok.. I've vented.
Indie911 is really pissing me off right now.
