Are the Germans rational?
Given the population ageing and the high level of per capita capital and income, it is not surprising that Germany has a savings surplus (an external surplus). What is abnormal is that, despite the lack of currency risk, Germany's external (savings) surplus is not being lent to the other euro-zone countries, but rather to the rest of the world. If it was lent to the other euro-zone countries, they could not complain about Germany's external surplus, on the contrary. It is on this point that the question of the Germans ’ rationality arises: is the fact that they refuse to lend their savings to the other euro-zone countries rational or not? Do the other euro-zone countries actually lack profitable investment projects, or do they actually have a solvency problem? It seems to us that the Germans’ stance now has become irrational, although it was rational ten years ago.
