Bounty hunters make good money precisely because few people do it. I think if all the unemployed became bounty hunters, the bounty fee would be very low.
It is already low right now. It is almost not worth it anymore, there is maybe a few bounties worth it. I dont remember when was the last time i got something meaningful out of a bounty campaign.
Even those that pay delay the payments for a very long time such that the price is almost zero before they distribute the rewards. Things like this makes me think hard about the future of bounty campaigns.
