Paddy:
query: If the country is on the gold standard then there is only so much gold. So does the economy become a zero sum game?
Not at all. The amount of gold may be fixed (or grow very slowly), but the amount of goods and services produced is definitely not fixed, but likely to grow very fast in a real free market. If the amount of
money is fixed then prices would go down. Even today the prices of goods produced by competitive industries like microelectronics keep on going down while performance increases - just compare your current computer to computers made ten years ago.
if we as a nation/large business/group etc. have more money, then other countries/groups etc must, by definition, have less?
'Countries' don't have money, individuals do. But there's no zero sum game here either. You could argue that the amount of 'wealth' is fixed, so if you have more of something then I must logically have less. In reality, thanks to production and peaceful trading, wealth is 'magically' created, so the result of the sum is not zero =]
