Someone explain to me why the same argument does not apply internally within the US. The imbalance of trade between Germany and other Eurozone partners does indeed create winners and looser. How different is this from states within the US. Since when did the US care about similar imbalances created between Alabama and say California? I'm sure there are arguments against this comparison. I'd be interested to hear them. That aside, I "feel" (based on living in Germany) that Bernanke is correct with his suggestions of where Germany could move. I don't think it will have much impact on the trade deficit but it will help Germany avoid more drastic emergencies in the future. The pay for workers is out of balance. The investment in infrastructure is not required now but important for its future. Currently it's infrastructure is far better off than other EU zone countries of similar size (and many times better than the US). But if it wants to retain it's significance 20 years from now it will need to innovate in infrastructure or be satisfied with being that country known for making old-world things at good quality. Germany definitely needs policies that encourage investment. Ideally though I'd prefer that not be in housing as stable housing is probably one of the primary social benefits in Germany. But as it stands with its undervalued assets it's becoming a place to be bought by others. Politically this creates interdependence which is NOT a bad thing but ultimately as the undervaluing continues Germans are just throwing away that value as value lost. In a globalized economy if they do not capitalize on it someone else will. Still, none of this will do much for the trade deficit. Because while it may take 20 years for Germany to push some of these changes, change within other EU countries to take advantage of it will take significantly longer. Then again, I'm not an economist so what do I know.
