I'm seeing more of these "JFK for president" posters going up around Amsterdam. (Does anyone know their source?) The optimism and confidence of the quotations is surprisingly bracing. The call to draft a man dead more than 40 years implies a disgust with present-day alternatives. Both the optimism and the disgust are characteristic of idealism, for which Kennedy is a natural symbol. He isn't usually ranked among the greatest of US presidents, but his relatively high showing is attributable as much to the enduring appeal of his idealism as to his achievements in office.
Idealism is an incredibly powerful motivation that grows stronger as the general social environment grows more cynical. It's like the gas in a piston that gets compressed until it explodes. It also works the other way: as idealistic programs fail (and of course, some will) and the speakers of idealistic words are shown to be flawed (and of course, all are), cynicism swings back into fashion.
As Jerry Maguire said, we live in a cynical world. And judging from public opinion, we the people who work in advertising bear some responsibility for that. And yet, we're not an especially cynical bunch as far as I can tell. So I'm wondering, what does a marketing idealist believe? If you were asked to talk about your work here, what would you say?
