I was incorrectly ascribing who is making these decisions. The artist would probably have to fight for anything beyond what the label offers. I have the same album on CD and vinyl, and there's hardly any difference in the layout and artistic details between mediums.
Yes, the labels are looking to make money, and that comes down to cost of production vs expected sales. The average consumer wants 33, so they're going to put their production dollars where the demand is. I guess my mind was processing the idea as an audiophile, and not as a businessman.
That's kind of the point of posting onto these forums, though.
