There would be changes, sure, but they'd be done through the "criminal outrage of the mob, led by leaders who [would be] either unscrupulous, deluded, or both." What changes are you hoping for? Are you hoping for a Star Trek-esque future of no money and people working, if they want, for the betterment of themselves and humanity? I don't think the technology is there, but I'm told we could feed and house the whole human population several times over if we made that a goal. What definitely is not there is the culture and society. I have no confidence that an outraged mob of US citizens would effect anything much better than the current system, but perhaps I'm just too pessimistic and haven't seen enough opposing evidence.

Of course, I am very tempted to see 'what happens' if we just let everything continue on the path of destruction. Follow your suggestions, vote for a Trump/Palin/Bachmann trio of president/v.p./secretary of state (not necessarily respectively), etc.
