Because people lie to make money and keeping up with everything is exhausting. Free-range is a term regulated by the FDA but who knows the last time a regulator came by and checked the farm that the chicken came from? How do you tell the difference between a farmer that actually cares and is doing their best to be free range, and a farmer that's doing the bare minimum to meet that regulated standard when you're in the supermarket looking at a package? Is there a difference between meeting the minimum because you really care about chicken vs meeting the minimum because you care more about money? Why is the minimum in the regulation set at that level?

But more unfortunately though, they're not the same price and quality. Whole Foods is called Whole Paycheck for a reason. I can get cheaper food from a different store that's good enough.
