Hi dig,
Sure would be nice to see things gather pace.
To some extent I think the Republican argument that confidence is an issue is true. But I think the US is almost irrelevant in this regard. The primary issue has been the possible calamitous failure of the Euro area. So removing that obstacle to recovery helps.
At the same time, I think governments are wasting huge amounts of spare labour capacity, which might be used to build infrastructure.
That's my top down approach.
But of course, the bottom up viewpoint is also helpful. Hope you are right.
