I'm curious, what are the things that happened during the Clinton administration that you think were short-term gains at the expense of long-term improvements? I've always felt that many of the fiscal policies of Clinton were in favor of long-term stability (e.g. specifically his tax policies and balancing the budget).
Now, with monetary policy and Greenspan specifically, I 100% agree that the "Greenspan put" was absolutely a disaster for long-term stability, but Greenspan was in office from 1987 - 2006 (originally nominated by Reagan), so I see his choices as pretty orthogonal to whoever was president at the time.
