At this point in your hypothetical, if we're still talking about the US dollar, you'll have a lot more to worry about than generating a return on your investment. If you think this is a serious potential outcome, then I suggest you forget about investing all together and instead start learning subsistence farming practices. Or you could buy Swiss bonds?
