How does Henry David Thoreau feel about standard US institutions such as the postal service and the press?

In Walden, Thoreau states that he does not like institutions such as the postal service and the press, as he believes the they do not contribute anything new to society. He believes that few thoughts and letters are worth the price of postage. He also believes that there is never new "news," just the same events happening to different people at different times. These views support Thoreau's beliefs that individualism and self-reliance are more important than society or any situation.
