Right. The current rules of the BLM are that they are to lease these lands for grazing and/or energy exploration.
The point stands. If ranchers feel they are being treated unfairly, they can buy their own land.
Ranchers get amazing subsidies from the federal government. If the government auctioned grazing rights like they did other public resources, there would be a lot less complaints. Someone who didn't mind the rules would just outbid the ones that did.
