Now, if only we can trigger this...
**** you. I doubt what I would make off of bitcoin would be enough to support all the people I care about who would suddenly be thrown in the poor house. It's not so easy to enjoy your wealth when everyone else is suffering. Sure, I told them about bitcoin, but I can't really blame them for being risk adverse during such uncertain times.
I understand your concern. What I have concluded though is that the biggest beneficiaries outside of the Arab world will be the American public. America has one of the healthiest and wealthiest of all economies but it is being strangled by the actions of the federal government. Most of that debt they talk about is owed to American citizens (50% or so at my last count) and that is only the official debt, if you add Social Security and the medical programs the total debt is something like 95% to the American public. They are funding themselves and the programs off of other Americans and to some extent funding it by devaluing the overseas dollars. Once this ends the US will have far more internal resources available than it currently has and will be able to rid itself of several hurtful monopolies. Most notably the money monopoly enforced by the fed. The federal government is not the people of America, it's well being is not necessarily yours. If you can rid yourselves peacefully and orderly of the sections of your government that have been usurped for special interests and oligarchies you should be fine.
Another thing to keep in mind is that it has already happened. Like a driver speeding to the edge of a cliff there was a line on the road where if he applied the breaks he would have been fine, that line has been crossed long ago. There were in fact several such lines. The first was the bankruptcy of Social Security and the medical programs. That happened quite some time ago, maybe even 30 years. Then there was the collapse of the dollar. That probably happened 10 years ago. Even if you get someone like Ron Paul, who in my opinion is the only man who even understands the problem, the entire monetary system will need to be overhauled. Ron Paul proposes lifting the restrictions on alternative forms of currency to let free market money emerge. Something like bitcoin would be ideal for this.
After the crash, if America does not turn its military might in on its own citizens, I think there will be a very strong recovery.
The other alternative, and this is the really terrifying bit, is that America is choked more and more over the next decade and supranational organizations (like the IMF through SDRs) prolong a collapse by shifting the costs to the rest of the world. This would keep the federal government in power for much longer and be much worse for the US and the world.
