According to the speaker, what is the problem with watching TV?

The average American kid spends more time watching TV than attending school. Elderly people watch TV even more than kids, since this is their main entertainment at home.
   TV is inherent in our lives. The problem is not with watching — the problem is with watching what: breeding violence and aggression through horror films or being stupefied by silly talk shows of many kinds.
   High quality TV is always positive. So, learn to switch on the right channel. The average American citizen watches TV as if it were a half-time job: four hours daily. By retirement, the average American citizen will have spent nine hours a day for years glued to lights on the TV screen. TV is powerful because it is politically oriented; it establishes public standards, it denies alternative thinking; it only simulates a variety of opinions, hiding back the ideology of mass conformism.
   Watching too much TV dehumanizes you, weakens your little gray cells, and makes your critical and reflective thinking abortive.
   TV plays with TV viewers, as if it were a cat and all of us were mice. We are eaten, turning into TV products, since we buy what the box recommends us to buy, we want to have such looks as our TV favorites have. We are programmed, we are told how to relate to events, how to feel in certain situations. All TV tricks are hidden from us, but their influences are similar to the invasion of a body by cancer cells.
   There is no chance to escape from the influence of television. But there is a chance to reduce negative influences of TV, selecting high quality programs and limiting time watching TV. Find an alternative to TV. But if you are a TV addict, stick to your addiction sincerely. Keep away from chewing your snacks or drinking your beer.
   TV does not have a negative impact on our society. It is a powerful source of information and a huge industry of entertainment that is inherent in our lives. Like anything, it is good when it is balanced with other leisure pursuits.
