You can't just teach people to enjoy art. I am an amateur photographer, I have a friend that paints. When my friends and I get together he will often have some painting or photograph that he has found to show me. We'll talk about it and have a good time, but, some of my other friends just want us to get off the computer so that they can use it. They may not want to be a part of our "art conversation," but, it doesn't make me like them any less, and I don't think that they are ruining their lives this way. They all have their own areas of interest.
By forcing people to "appreciate" art you will find that people will enjoy it even less. They don't like being told what to think... nobody does.
