To sell to whom and at what price?
I think you may be missing the overall effect of a devalued currency.
Will a devalued currency make domestic goods cheaper than foreign? Absolutely.
Will anyone domestically be able to afford those goods? Most likely not.
Phrases like "feeling the pinch" and "minding your money" will become incapable of describing the transition for a normal, tax-paying American.
If our currency is devalued, oil becomes more expensive...by an astronomical amount, pricing everyday citizens right out of the market. How do you get to work? How do you sell your current house to move closer to work in an economy where no one can even buy? Even worse, youre already close to work but your company fails or dismisses you? What then? Back to square one.
A devalued currency certainly makes our exports cheaper, but kindly ask who is going to buy them? We are one of the few open markets in the world, most governments have tariffs and protectionist policies that "level the playing field" with their own domestic goods.
No easy answers to any of this, really. Two that I see: isolationism, which is the way I always thought it should be, and the one I most loathe, single currency.
