D&D is in my opinion very like modern day tourism. The adventurers are basicaly heavily armed backpackers wandering the earth to see the sights and hear the sounds of wonderous places and get themselves into some adventures.
So what you're saying is that adventurers are basically Australians with a homicidal bent?

Seriously, I don't worry too much about the economics scale (we don't play so long we can afford to!), so when it comes time to buy things I let the party have them at the PHB prices.
When and if the PCs ever need hirelings and lackeys, I figure I'll give them Profession skills in whatever they need to know, and they all take 10 -- thus a 1st-level stonemason with Wis 12 would get a result of 15. Of course, he's taking ten times as long as he could to get it right. Only a master craftsman can whip something out and be better than an initiate who spent a lot of time on a comparable item.
Someone argued that it was unrealistic to have peasants maxed out in a skill, because peasants don't get to pick and choose like PCs. I don't think so. I think they ought to be maxed out in Profession and Craft, at the very least.
Besides, by the book, the only way to gain experience is to face and defeat (any way possible) a foe. So, to be ridiculously simplistic, the only way to get better at what you do is premeditated homicide. How many folks does a carpenter kill in his lifetime?
