It's not racist. That's ridiculous.
But all it takes is a brain to find fault in the commercial's motives.
The independent farmer is dying in this country. They're being crushed by giant corporations and a lobby that holds more sway than almost any other political player in DC. An end of era is coming, one of the last true pieces of American culture, the farmer, is being demolished in the name of corporate greed. The Monsantos of the world, with the assistance of an uneducated American public, are making billions from putting people just like the ones you saw in the ad out of work.
So rather than talk about that, let's spend $4 million dollars on a 60 second commercial that exploits that depressing reality in order to sell a truck for a company that's no friend of the independent farmer. It'd be like Mercedes Benz doing a commercial in honor of all the holocaust victims.
Shameful.
