"A businessman is the only man who is forever apologizing for his occupation"

This quote by Gilbert K. Chesterton suggests that business people are frequently regretful for their occupation. This might be because of the unfavorable undertones associated with the term 'businessman', such as greed and selfishness. It could also be because of the pressure that entrepreneurs deal with to be successful in their field, and the regret they might feel when they don't fulfill their own expectations. It might likewise be because of the way that business people are frequently depicted in the media, as callous and unconcerned. Whatever the factor, this quote suggests that business people are often apologetic for their occupation, which this is something that is distinct to them.
