You know that epic John Wayne-type cattle herder who sits out in front of their homestead on horseback with a Winchester rifle resting on their lap? Yeah, that's not really how it works anymore. It's more likely that you'll be sitting in the cab of a hybrid pick-up truck, filling out a bunch of paperwork.
Ranchers are also at the very low end of the food production line. Now that corporations are in on the food action, the mom and pop rancher is struggling to survive. If you're one of the lucky ranchers to own their own land, get ready to defend that land from corporate takeover.
And let's not forget all that wonderful government intervention (source). From the FDA's regulations on the food supply, to the Environmental Protection Agency's rules about farm waste disposal, to the IRS and its tax collectors, you're probably going to have more interaction with the Federal (and State) Government than you'd like. On the bright side, your congressperson will routinely be fighting to get you a bigger tax break, so at least you've got someone on your side.
That is, until some corporation pays them to vote against you. Ah, politics. It's all cow poo, even when it actually involves literal cow poo.
