They may hold opinions which are diametrically opposed. They may come from places as far removed as Biloxi from Kuala Lumpur - but they all wear a suit and a tie. The business suit is a universal symbol of status and position. The Torah tells us that clothes lend status and splendor to a person. In other words, clothes give a person honor and status.

A soul and a body. The soul wants honor. The body has a different agenda. The body isn't interested in wearing a suit, because it isn't interested in honor. Honor implies responsibility.
