Well, when it comes to politics, I think things are just aggregations of individual people and their power. It's more convenient to THINK in terms of macro, the same way that it's easier to drag a file to the trashbin on the desktop than it is to find the index table on the drive and zero out the entry....

Like I think about how hard it is to increase housing. "The macro" level, though, is really just a lot of individual property owners pursuing their narrow financial interest in keeping property values high by keeping demmand high.
