Blame affairs on evolution of sex roles

Tolerance for male adultery is certainly at a new low. In letters and diaries written during the Colonial and Revolutionary eras, men routinely bragged about their extramarital conquests -- even to the brothers and fathers of their own wives! In the 1850s, it is estimated that New York City had one prostitute for every 64 men, while the mayors of Savannah, Georgia, and Norfolk, Virginia, put the numbers of prostitutes in their cities at one for every 39 and 26 men, respectively.

Part of it is probably a sense of entitlement. Powerful men have "people" to take care of the mundane details of life. They are briefed on the names and backgrounds of whomever they meet, told when it's time to leave, and extricated from awkward encounters. Someone else keeps track of appointments, money and time, fetches whatever they have forgotten at home, makes excuses when they change plans, and picks up after them when they leave a room. No wonder they get careless about picking up after their indiscretions as well.
