Strong, obviously, right?
How about for currencies? Would you rather have a "strong" dollar, high in value against other currencies, or a "weak" dollar, lower in value against other currencies? Well a strong dollar seems to be a matter or pride with many conservative politicians, and their richer constituents, who tend to buy more luxury goods from abroad, and travel more.
But the fact of the matter is that a "weak" dollar is much better for our economy. A weak dollar makes our products cheaper than our competitors, both abroad and domestically. We produce and sell more, and employ more workers, when the dollar is weak.
The Chinese know this very well. They keep their currency, the rembibi, artificially weak, so as to spur their economy and continue its incredible growth. It's their weak currency that allows them to experience huge trade surpluses year after year, and accumulate huge dollar reserves.
Right now, Greece, Spain and Portugal would love to weaken their currencies as their economies struggle, but they can't. Their currency is the Euro, over which they have no control.
So the next time you hear a politician railing against the weak dollar, maybe you should think twice.
