On the question "Why don’t people watch good TV?" the answer is that people do watch good TV, but the overhead and costs associated with TV on major networks means that they need amazingly high ratings to stay afloat. Channels like AMC and Showtime have such low costs that they can be profitable with slightly more viewer-ship than a local TV station, and they can focus on developing low-budget high quality TV shows (Dexter, Mad Men, Breaking Bad) and if they find an audience they can adjust the budget to ensure that everyone working on the show is happy.
