What if oil went to 3, 4 or 5 dollars a gallon tomorrw? OMG! Wake up tomorrow and find lines miles long as people start to hord gasoline. Think of the run at the bank as 200 million drivers in this country show up to get cash for gas! The economy would sink in a flash. Would you go to work? How long would work be there before it folded? How long before the grocery store shelves became bare? In last winter's ice storm it only took A FEW DAYS for them to get pretty slim from the lack of passable roads. How about finding that grocery prices hit the roof and a loaf of the crappy white bread was 10 dollars? Your pay is not going to go up, that's for sure.
What would we do? What could we do to survive and help each other without allowing society to degrade into a Mad Max rerun? Are Americans able to care about each other enough to help rather than kill and steal from each other? I have seen no indications that we are able to do much else. The folks in my area are hard line nazis, its "everyone for themselves and if you can't make it its your own fault" around here as far as I can tell.
I think that perhaps a post dollar world would have to depend upon bartering for more economic exchange. If the dollar is worthless and there is nothing to replace it there would be little alternative. But, with so many people living in cities with little real value to use for bartering (not much use for a programmer when no one is doing business, nor maids, nor gas attendants, nor waiters) What can people use for currency to get the goods they need in a city?
I live in the countyside, very close to the burbs though. I have some farm animals but not enough to survive with. And how do we pay our tax bills, water electric etc... we need cash for that.
I'd like to start a connection point for discussions on the topic of a post capitalist world. How can we make a better future through our efforts today?
