How does henry david thoreau feel about standard us institutions such as postal service and the press

He thinks both postal service and the press are not necessary for living. Even more, they are redundant. He says that he doesn't need post-office at all, as most of the letters that people send and receive are worthy of sending or receiving. Also, he doesn't care about the media, as they never bring any news worth reading. All events and occurrences that the press writes about are mere gossips. For example, a person doesn't need to read about hundreds of murders or robberies to find out that crimes happen.
