First off, I am going to assume you are an American (the dollar really gave it away).
You are a capitalist, that is what America was built on. Pour your money into any currency, stock, or futures purchase you want. If it is a good investment, your government will get it's cut off your income. That's the american way.
As for feeling bad...really? American good and services look relatively cheaper compared to other goods and to the same american goods and services a short while ago. That means more units sold for just a small dollar dip. America would actually make more money.
So don't feel bad, seize the opportunity.
