The problem is governments getting way with putting responsibility on "Brussels", when they are fully part of the decision making process in Brussels (and often with an explicit veto right and, in cases where majority voting exists, an implicit veto nevertheless if they scream loudly enough).

That's a problem of national pundts (and the opposition, but they know they'll play the same game at some other point too) letting them get away with it, and the public ditto.

Again, with a huge chunk of our legislation coming from Brussels, the single most important decisions by our governments are the tradeoffs they make in Brussels, and voters should look at these a bit more closely.

In the long run, we're all dead. John Maynard Keynes
