In "Fahrenheit 451," why does Faber think that the people, not the government brought the present state of affairs upon themselves?

He says this because the people, like him, who saw it coming did nothing to stop it.  He says he saw the trend coming and he could have spoken up, but he didn't and now, he continues, he is one of the guilty.  The point that Bradbury through the character of Faber is trying to make is that when people don't speak up to stop the wrongs they see being committed, then they are as guilty for those wrongs as the ones committing them are.  He is warning the reader to avoid complacency.
