An extreme example and still totally unconvincing. I don't speak Spanish but would like to learn. My wife's family doesn't speak spanish but their nanny does. My brother doesn't speak Spanish but watches futbol. My dad likes to stop on telemundo periodically. My other sister has a few Spanish speaking friends. And on and on.
Everyone has their own utility and I guess we just differ on ours. I don't want to generalize but I personally wouldn't pay more to have a set of Spanish channels. Arguably if there were too many Spanish channels I'd pay less since navigating my TV would be too difficult.
