Ermmm..... Interesting article, and I agree that the ennui of the American character is particularly weird right now....
But I don't know if "collapse" is the right word.
I think people still care. I think the country still cares. I think there are reserves of strength that haven't been tapped yet. I think American politics is in a weird "things-are-so-fucked-up-that-nobody-can-fix-things" mode right now, but given a strong candidate, with an agenda, I think it'd bounce right back.
