Do the influential visionaries, pragmatists and balance strikers comprehend the fundamental nature of creativity?

Do they comprehend that 'the creative impulse has the potential for not only positive, but also negative, expression?

Would they, if having taken an infinitesimal dip into this deep and limitless ocean, better appreciate that creativity can bring into being both ecstatic dreams and horrific nightmares?

If both influential and grassroots people were to become convinced that somehow we have to change the way we do things, and that change is in fact imperative, how would they go about it?
