I think the new currency will be food. because if we dont fix our infrastructure in the usa with in the next 25 years their will no way to get food and water to stores or our houses. the roads, water supply systems, damns, levees, and bridges are all aging rapidly in the usa and we are not keeping up with rebuilding, and maintaining them.
I watched an excellent documentary about this on either the History or Discovery Channel. We are in a very big bind and nothing is being done about it.
It's, uh, not the greatest situation in the world.
