The reasons the 50 States of the USA manage with a single currency, Fred, is quite simple. Here are just a few of them:
- They form a single sovereign state with one government.
- They have one set of fiscal rules which are adhered to so that their economies are “pooled”. This means that there is only one deficit or surplus for the nation and not individual ones for California, Texas, New York, etc.
-The purchasing power of the Dollar is not state-dependent (although there are geographical variations as there are in most countries).
- The interest rates and exchange rates are not determined so as to suit one or two states whilst being completely unsuitable for the remainder.
- Prices, productivity and competitiveness do not exhibit wide variations which are particular to one state of group of states.
- Most importantly the US$ was set up under a single government and set of rules for the benefit of the nation as a whole, and not cobbled together as a ego trip for a few politicians who had no regard for the people and who pressed ahead despite being warned that the latest scenario was a very strong possibility.
Certainly Germany and France recognised the benefits (to them) of establishing the Euro. It was quite simple: lend the peripheral nations huge sums, the likes of which they could only dream of before the single currency, at ridiculously low and very attractive interest rates, and encourage them to use the cash to buy your goods and services. Simples! The only problem was that none of the stupid gullible politicians of the borrowing nations could see beyond their noses (or in reality the next election) to realise that one day those debts would fall due for repayment.
The Euro is being kept on a life support machine by the stronger nations, in particular Germany, because the prospect of its collapse (which is now virtually inevitable) will lose them all the advantages they saw for themselves before the set up. The only question that remains is whether the end will be painful, very painful or excruciating and the longer the life support machine is left plugged in the more painful and prolonged the end will be.
