I exactly thought of Fahrenheit when reading the first sentence. In the story there is a really good image involving the zipper. Since the zipper takes less time to close than buttons take, there is those few seconds less EVERY time you zip/unzip a sweater that could be used for thought and formulating your own opinion. This is something I personally fear. Due to lack of time for thinking, people will be more easily manipulated by the media and anyone (with the patience) willing to take advantage of the people in the downtime-less society.
