It only allows the wealthy to do tourist hunting, ie hunt as non-residents. One could always move to the state that they want to hunt in if that was a major priority for them. Personally I don't think I will ever be able to afford 20k for a brown bear or dall sheep hunt in AK, that said I have expressed to my wife that I really want to do this and we have discussed the possibility of moving to AK for a couple of years at some point so I can do all the hunts on my list. Not saying we will do it, but maybe.
Further, if you are hunting for meat then non-resident hunts don't make sense in a cost benefit since, I'm sure you aren't going to Alabama to hunt whitetails all the time correct? Therefore one can assume any nonresident hunt is a trophy hunt, with either the rack or just the experience being the trophy. So given this fact states charge less for there own citizenry to harvest meat and more for others to have a trophy experience. The ridiculous cost, and I agree it's insane $6k for a bison in WY... crazy, is based on market pressure and right now the market has shown that it will support non-resident tag prices far in excess of the current price.
I do lots of hunts out of state and I bite the bullet because I would rather trudge up a mountain in MT or ID than sit on a beach in mexico.
Yeah the situation sucks and doesn't look to get better, but in all honesty I think it's as it should be and I think we haven't even gotten close to peak non-resident prices.
