Your getting a bit dramatic here no?
There hasn't really been that much money in the world since the 60's anyway.
As for our economy, it was propped up through Quantitative easing where the BOE bought debt back from companies who initially bought government bonds in the first place. That's the main reason we seem to be stable at the moment, essentially printing money and fiddling the books to pretend we haven't although it still has piled up our own debt which has to eventually be paid back by the tax payer. Well that's is you abide buy the 'laws' of money. I mean lets just write it all off like we did for half of Africa and start afresh.
As for the rest of the world, who knows, most depends on the demand for goods from the West. It's all a Ponzi scheme anyway, you have products to sell, I want to buy those products, we pay you money, you pile up lots of money, your money loses value over time due to inflation, you invest your money buying our bonds, we pile up more debt, we spend your/our money back to you. And on and on.
