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 fuck it, we're doomed, every man for himself...but here in America, we don't puss out quite so fast.
