I agree with the OP. I invested in the 6-prop pants plans and although the GAH says that I should be making money off these items, no matter how much I undercut, they just don't sell. I'm actually losing money crafting.
It seems like we're back to the Diablo 2 standard. There's a very small group of players with "godly" gear and hundreds of millions of gold, and then there's the rest of us. We missed our chance to "buy in" by exploiting resplendent chests, botting, and doing pony glitch runs. As a result, all the best gear will be forever unattainable, because we can't make money, can't save up, and the only way for us to get drops is to legitimately farm, and we all know how well that goes. I'm just glad I got my wizard up to 60k DPS while I could, but it seems like he's stuck there. Time to move on!
