Singer's ethics through the radio

An essay about a short story called "The enormous Radio" by John Cheever. You can read the whole story here.
Please read the source text before reading my interpretation.

Jim and Irene live peacefully without anything distracting their normal ways of doing things. Jim goes to work and Irene takes care of their children. Everything is just fine. Everything is average.
 First the new radio is only intriguing entertainment for Irene, but when she becomes aware of the problems in the neighbourhood she becomes anxious. A question awakes in her mind as well as in the mind of the reader: are we responsible of other people's lives?
 Is it all right not to offer your help if someone is in need of it? Does an individual who lives in a welfare country have a right to live their white bread life using the limited energy sources of the Earth? Is that kind of behaviour morally right? Is that plain laziness or a learned habit? To most of the Western population the fear of disturbing other people's privacy is automatised. One can also ask: is this just an excuse?
 Either way, Irene starts to feel uncomfortable knowing what her neighbours' lives are like. Jim tells her not to mind anyone else's business; other people's worries do not concern him. He is protecting his wife and asks why she has to care so much. The answer is simple: she is humane.
 The unhappy things still exist though we ignore them. The misery won't go away if you close your eyes and ears from it. The world doesn't either get any better if you sit at home worrying about the state of things, buit it's good to be aware of them and act wisely when it comes to any kind of choices.
 The radio and its effect gave the married couple a reason to quarrel about the things that they had kept for themselves. Once the top of the iceberg is on sight, all the rest that has been hidden underneath the surface of their seemingly safe, average life is revealed.
