There are advantages/disadvantages to a strong or weak dollar. That is why you see business trends change with the dollar, weak dollar its advantageous for exports and foreign investment in the U.S. (foreign dollars buy more than they did in the past) and a strong dollar its advantageous for a imports and foreign investment by the U.S. in other countries (U.S. dollars buy more than it did in the past).
I would think a stable dollar is most important, NOT cycling up and down, as well, I think a strong dollar is "one" of many indicators of a relatively strong economy compared to others. A strong dollar alone does NOT mean the economy is great, its one of several indicators people should be looking at. Like most in the thread, I really don't enough to state a definitive opinion.
Keep in mind, intentionally devauling the currency is something banna republics have done to solve their debt crisis. Half the value of their currency, and they've halfed the amount of debt they owe, they also have halfed the value of their peoples savings and retirements at the same time, that is why you see riots when the government does this.
Something to keep in mind as we continue to build a mountain of national debt, at some point other countries that buy that debt will decide its NOT a good investment anymore, and if one does it, likely the rest will too, and we become a banna republic overnight.
Jobs going overseas, sure you can argue the strength of the dollar is a factor, BUT its minor at best. Jobs going overseas is the result of societal and industrial evolution of the nations of the world, and global trade and interlinked economy. More advanced countries with better education and higher standards of living, should be doing the more advanced and complicated jobs and services and the developing nations should be doing the simplier and less skilled jobs. I know some people don't like that, and of course nothing is perfect and you can find examples of abuses, BUT, sorry the U.S. can NOT live stagnant in the past and isolate itself and ignore the rest of the world, there would be even less jobs and prosperity.
