The presenter was having a nervous breakdown and told everyone watching, if they were not happy with the way things were in their lives, they should stick their heads out of the window and shout "I am as mad as hell, and I ain't going to take it any more".
Well it caught on very very quickly in the city and the presenter became a star, with millions tuning in.
However my point is, the current posts seem to mirror the feeling of these people in the film, and possibly a lot of people in the country. However they seem to want more than stick their heads out of the window and shout.
