When The Usd Collapses...

Usa debt is about 15.6 trillion last month,
China is the stronger power backed by Pms these day's, pretty sure the had more efficent new amrys traing and sent to the east islands of china,(defence).
As for the chip, many talked since 1980's about this, there in our cats,dogs, and keycards for A.T.M and pertucees that it seems we might be next?
Bit hard to microchip 7 billion+ people, but if there were fewer?

You can see where I'm going here, but in the end it makes sence they will chip us( money/credits,health data,history & convictions) and gold and silver will probabally become a black market!

Barter? Are you kidding? The whole idea of currency is because barter is not very efficient mostly. I mean if I have some fresh fish, and want to trade half of them for some rice to make a sushi roll, then I am going to need to find someone else who has rice, and wants fish. Not all that likely really. Much better is to have a medium of exchange that everyone basically accepts, then I don't need to worry that the guy with rice wants a fish or whether he wants some carrots because he will take the medium of exchange and use it to get what he wants.

If were bartering its because everything has crashed and its doomsday preppers mode.

100 years from now there probably wont be cash and coins for everyday use or a minimal amount as everything will be electronic

@Everyone disagreeing with my sentiment: Sure, we'll still have currency on a passing level, because the only "hard currency" in barter is food, and as you guys pointed out, even that isn't universal--I'm not going to weed your garden for milk and cheese, because I'm lactose-intolerant, and you may not accept my offer of weeding your garden for chicken and bell peppers because you have one of those fancy bubble-gardens that does not grow weeds. You're not going to pay your factory workers in food and not have a revolt, because they'd have to choose between their precious food-pay rations and other life necessities.

However, I do believe that barter will become a substantial amount of our trade as the large corporations collapse under their own weight and we return to a small/local business model. Like I said, there was a point in time when I preferred to be paid in food and winter clothes because that was more valuable to me than whatever money you might offer. During that same period of time I edited a master's thesis for the following wage: $100 in cash to be paid upon completion, two meals, and a pair of jeans up front. Nominally this was for six hours' worth of work, but in reality it paid for about ten (I had to cross-reference her citations, etc. and we did not share a discipline). The cash paid for groceries, gloves, and new sneakers because the duct tape on mine was falling apart, but it was the meals and jeans that were most valuable to me--hence why I requested that payment first. If the dollar's current trend keeps up, that's going to be true for a lot of people.

@IndianGoldEagle: Yes, we must see the bigger picture, but the local counts for a LOT. Everything you do even at home is a small microcosm of the world. The small is a metaphor for things happening on the global scale. Sorry to generalize, but I've found this to have at least some truth in it.

Dohmenator you are correct. History should not be ignored. Just a couple examples would be 1920's Germany, 1990's Argentina, 2000's Zimbabwe. Coins became far more valuable than their face value.

Simpler household items could be like a currency in a bartering society... bars of soap, rolls of toilet paper, tubes of toothpaste, etc etc. Fish would be a less usual item in commerce.
