Another dangerous aspect of this form of government is the control of information. Think about why books are so influential and valuable; if you didn't have the internet, what is the best source for research? By controlling what is written down, the members of the F451 Government have essentially limited the average citizen's ability to access information, data, or even entertainment.
By doing what the government demands, yes, you will have few difficulties, at least on a surface level. By looking at Montag's wife, one realizes that the average citizen is very content to come home, watch the multi-wall screen television, and envelop themselves in a media-controlled world. Even the interactive shows offer nothing of substance; it's a false feeling of belonging.
However, should one decide to go beyond the narrow confines of one's job or allowed leisure activities, then trouble begins to brew. When Montag had a series of conversations with the girl down the street whose families harbored books, his sense of questioning and curiosity was met with fury by his wife. In fact, she eventually turns him in as a traitor to the firemen. People are so afraid of what is unknown or different, that they'll gladly betray those closest to them in order to maintain the status quo.
This type of government--all-controlling and manipulative by fear is always dangerous. The government will continue to force people to do things they don't want to do in order to keep the people down, and all the while the people are waiting for some brave person or group of persons to stand up and rebel. It's just like 1984 or Communism in Germany under Hitler. The cause of the war is always discontent. The few people in this novel who did not give up their books, the ones who memorized books to be written down at a later date...these people who are the discontented will keep the memories of the past alive and teach the younger people who will listen. There will always be a rebellion in a government like this. People are not robots. They want freedoms.
