Indeed. As the problem is mainly the competitiveness of France vis-a-vis Germany, you have to wonder why Sarkozy is going at the ECB (which will not affect that relationship much), instead of working for a common employment, industrial and redistribution policy, as Migeru suggested in your thread.

My guess is that he just wants control. It's always been sort of a strategic aim of France to bring the ECB under political control, but its independence is a sacred cow for Germany.
