What the heck does that mean, "we already have several news channels." We aren't talking about adding more. Further, you are not correct, Fox News is NOT in the lowest essential package. You happen to be in the minority about Fox News, as you would be about TNT, USA, etc. They are the most watched channels, not having them in packages would be totally counterproductive.
Your premise is wrong. No one who wants Satellite or Cable is going to want complete A La Carte, to think so means you don't understand it. The very thing you are railing against is what keeps a channel no watches like MSNBC on DISH. If you watch MSNBC, you likely won't be because there is not a chance they will exist when people have to choose to buy it. Fox News will still be there. CNN? Questionable. Then you will be here complaining DISH only carries Fox News.
If people think fees are high now, just wait till you see what channels would cost, including fees if everything was A La Carte, at least for those channels still existing.
