I have been trying to understand why German politicians are willing to throw so much money at this problem, clearly against the will of the majority of the electorate. Here is the best theory I can come up with: Germany relies on exports. They need countries which buy them - having everybody use the same currency benefits trade. But more importantly, banks of strong countries like Germany, France are lending money to the fiscally weak countries so that they can import the goods they produce. This benefits their industries. However, why would the banks take on credit when they can be quite sure that these countries will default sooner or later? Well, there has to be some guarantee/assumption that they will be bailed out by the central bank/governments. And of course this happened.
So German banks and the export industry, the two entities with the biggest lobbies, get subsidized with tax money. The weak countries won't ever develop their industries and become competitive.
What is your view?
