It may if one uses their time learning and enjoying other things.
Too many people claim an elitest moral high ground in admitting they don't watch or own a televsion...as if people who watch a lot of television are somehow lower in intellect and judgement....when it's simply a case that they can't afford one, or can't afford the cable bill.
And furthermore, if you had cable, you could enjoy the Discovery, History and a wealth of other educational channels.
Go for a year without television and report back. Unless you've experienced it for yourself, you have no idea what you're talking about.
We have "enjoyed" them for years, in hotel rooms and during stays in at the homes of relatives. We have enjoyed their programs on DVD and video, on our own terms. I don't judge people who make it a daily habit to watch hours and hours of television -- but I will certainly and quickly flock to and identify with the rare folks who have experineced what I have -- life in America without TV -- not for a week, not for a month, but for YEARS. It is simply amazing and indescribable how it enriches your life. That is, simply, the way it is. I sincerely, passionately recommend it to any thinking person or family.
Anything you can learn on the History or Discover channel, you can learn BETTER by reading books or taking classes. More important, you can TAILOR IT to your individuality. Sure, "... if one uses their time learning and enjoying other things," as you way, but the thing is, when you can sit passively and have pre-packaged edu-tainment delivered for the cost of cable per month, you will never desire to use that time learning and enjoying other things on your own unique terms.
The thing that happens is that touchy people immediately take offense when people like me talk about how great life is without TV. Touchy people immediately assume I'm taking an "elitist moral high-ground." I say, that's their problem, their perception, their choice to be offended.
