Right to Own . . . surprise, surprise, our local TV station came up with something I was unaware of! A farmer bought a new tractor, and while he and his son were "taking it for a spin", his son was on his cell phone . . . and said, "Dad, did you know you don't own this tractor?" He bought it, he paid for it, he gets to use it . . . but he cannot modify it, he cannot repair it, and in fact he cannot even try to learn how to repair it! And these circumstances, it turns out, apply to a lot more than very expensive tractors! Try computers, cell phones, appliances . . .
