N.YC is now one step away from becoming another reddit. All we need now is one "bush/cheney is evil" story on the front page and the transformation will be complete.
After we're beaten up and attacked with Tasers at the door of Best Buy for failing to show our papers but not before we've seen the best picture of a tree we've seen all day.
From what I understand, currencies tend to reflect purchasing power parities. Something as arbitrary as the currency used in oil sales won't change US productivity, which is the most important component of wealth.
So I'm not too worried about this kind of thing.
I can imagine some disruption caused by reaction to this though, especially if congress tried to solve the problem.
Either way, I have a mortgage. Nothing would make me happier than to have my debt mean less which a falling dollar :-P
I'm not saying it'll happen in the US, but anything's possible (especially to degrees, see current subprime crisis), especially with a reckless leader at the helm who doesn't understand that we need to, you know, actually pay back all this debt we're accumulating as a country one day.
You're right, that's what I'm talking about. A dollar fall would hurt my purchasing power on imports and when I travel, but that is short term. My original point about PPP is that these exchanges adjust to match levels of wealth. There is little reason two countries with similar wealth should have different purchasing power on imports because of their currency.
I don't know enough about inflation vs. currency fluctuations on comment on the differences.
Fans of the 'Arab pullout causes dollar collapse, worldwide financial panic' genre may want to NetFlix 'Rollover' (Kris Kristofferson, Jane Fonda, 1981). And also stop posting such stories to YC HN, unless they've got a hacker/startup angle, like "How to profit from the coming financial collapse with AJAX Facebook Apps!"
