At George Washington’s home, the Mount Vernon Ladies Association is evidently taking lessons from TV advertisers, some megachurchers and others who act as if the whole citizenry were made up of 18-to-34-year-olds. And they have a particular kind of 18-to-34-year-old in mind. They presume that members of this age group are easily bored, uninterested in anyone who is not like them and incapable of imaginatively engaging with anyone of the past. No doubt the Mount Vernonites have also consulted the requisite market surveys that urge them to adapt to the interests of this cohort. But many in that generation do not fit the market stereotype, and we are all victims of the assumption that they do.
