Never going to happen, but what will happen is those who are in areas that have higher costs of living will cease to do them. It is like any industry, if you can't make enough money people move on. And this is no different, the equilibrium will be found constantly, and will always be evolving to find a new equilibrium.
It seems to be more correct that when the profit decreases and no.of participants increases ,people will move on for new resources as in any other business.
Therefore it becomes compulsory to make the rules and regulations more stringent to participate in Bounty.
