Are you sure you'll be paying taxes twice? AFAIK, countries signed on mutual tax treaties only tax you for the difference between the domestic tax rate and what you paid in the other country. Being that US has a lower tax level than Germany, this difference will be negative, so effectively zero US tax. I think the problem with US tax codes is that as a citizen you need to pay tax for any revenue you collected regardless of where you are physically located, but taxes you paid in treaty countries are subtracted from the total.
