Did you follow it to who is posting that and in such a misleading way?
You must not have read it, or you would have realized that they lump all the BLM costs of managing those lands for ALL uses and then say the ranchers are the ones to profit from that.
They first forget that the ranchers have as many expenses, many of those 50% are cost shared, plus the ranchers are PAYING for the permits.
The truth is that the ranchers are PAYING for grazing and maintaining their permits and all the other they have to do for the multiple use of those lands.
If they didn't already had private lands mixed in there, where they have to use that BLM land, they would NOT rent it at all.
Even at what seems a low rent, compared with others, that amount is still more than they would pay somewhere else, when you count that they only get to graze a few weeks and have many, many more costs than they would have on deeded land.
If it was not their homes and had been for many for several generations, they would not want to stay there either.
When you look at the source of websites like that one, you have to question what they write and then you will see it IS questionable.
