Wait please, I'd like to expand on a little tangent/sidenote. See, if the whole world is united in peace and diversity, you'd have the United States of the world. Each region would be in a different "state" due to it's culture. You'd want to keep diverse cultures I'd think. It's a good thing. There would be no nations because there would only be one government. So keeping that in mind, "statehood" would be the correct terminology. And they're united. Got it? During this state you wouldn't have any wars. I know what you're thinking, put it on hold for a second. You'd have terrorist. Actually "errorists" by this point. People that don't agree. Where the world just doesn't compute for them. We'd know for sure that we were right because we'd keep each other in check because we'd be a responsible society by that point. So you'd have errorist and misunderstandings. Actually they are all misunderstandings now aren't they? Natural disasters and malfunctions and straight up violence for sport depending on the culture. Let's get back to the economy.
...a world standard. The good old green back. And we've also got quarters. I'm thinking of the quarters we have for each of our states here. Each state would get its own quarter and each quarter would be of equal value to the next one. Let's just do a dollar. Sh*t, ones you can print out with your own face on them even! So my Delaware quarter, the first state in the Union, is equal to the final state to join the Union, say... the state of Taliban. Money flows to and fro. "Hey, buddy, nice doing business with you!" Everything is going great. Because at this point we realize that a real, functional economy is based on trust. (Thank you AIG. And the others to follow. So wish there was a 'Mean Inc.') Products have a clear and transparent value that is verifiable. Things are f***ing great.
And then the unthinkable happens. Kinda like 9/11. Someone does a bad thing. And things get stirred up and tempers flare and people blog about it and upload all sorts of sh*t and there's demonstrations, etc. If the state that does the social misdeed chooses not to leave the union (which would be legal however a possibly meager existance) and things aren't easily rectified, this "moral economic stability" would be effective: Don't do business with that state. It would be considered "dirty money." Don't do business with the "Taliban State." They would "suffer" a lower quality of life economically and progress would be slower both technologically and culturally. It would have a negative impact on that society. It shouldn't bother the rest of the world because, well, you don't need money to survive and everything is relative anyway. But the state that did the misdeed would automatically be incentivized to "get their act together." To be able to work out the problems, find a solution and get back in there with the rest of the world because it is good. Incentivizing everything in the proper sequence will be understood by this point as well. So, if some guy who stands for something that you think is wrong tries to sell you something you just say, "No, thank you. I'll take my business elsewhere. I don't want your dirty money."
And that, dear reader, is not only the solution for the future but it is also the solution of the past and most importantly, that is the solution for right f***ing now.
