I know recently the US Dollar has slipped, but I always used to wonder why in the previous years the pound was always stronger than the dollar. It doesn't make sense when the US is much more wealthy and has a bigger economy. Any quick answers?
I'm not sure unemployment rates have much effect on currency markets; and the US economy is certainly not in a slump. But it does have a tremendously high trade deficit with the rest of the world, and also its interest rates have been low for a long time, though are currently being raised. I think it these latter factors that have depressed the Dollar in recent years.
Have to agree with Bob a Job, its not the unit of currency that denotes (bad pun sorry) the value of a currency The Yen is a strong currency but currency unit for currency unit it is worth less than the Aussie Dollar.
