The economic aspects of the DnD game, IMO, have been really poorly thought out. Plus, there's this tradition of making any economic transaction completely to the detriment of the PC. I think the reasoning is two-fold:
1. PCs have too much money and if you don't have NPCs abuse them economically they're all going to use their money to buy vorpal blades and take over the campaign world.
2. PCs won't want to go adventuring if they can sit at home and do nothing and make just as much money.
Worse than that, I think some of this reasoning has crept into the core rules themselves.
So the DM in the OP might be making bad decisions, but it's not like he has a lot of tools to work with. Perhaps show him the business rules in DMG II and see if you guys can agree on something there. The idea that he says bad things about a +30 perform check seems weird though.
Economic things in DnD can be challenging to DM, so maybe help him out with some info and hopefully he'll step up and make some decisions that make sense. IMO the secret here, like with a lot of complicated DM decisions, is to try to be cooperative, and respect where the DM wants to go with the campaign.
