You really ARE optimistic!Well, I hear you, but your alternative is nihilism and despair.
You can just default to that NOW and put a bullet through your head, or you can hope for the best and do your small part to ensure stability and see what happens.
I don't know what your situation is, if you have kids or a wife or who your real life friends are, but chances are there are people less intelligent than you and/or less confident and you can be the voice of reason for them, the person who offers rationality amidst the chaos. You can CHOOSE to be the strength someone else needs; the flashlight that allow them to see clearly through the fog.
Or, you can just say f*** it, we're doomed, every man for himself...but here in America, we don't puss out quite so fast.
