Alexander Hamilton famously predicted that the judiciary would be "the least dangerous" branch of government. How's that working out?

The Supreme Court stands as arbiter over a country increasingly unable to govern itself. Americans can't agree on the meaning of the Constitution or even the rule of law. Are the nine high priests enthroned in their marble temple the saviors of the Republic or the pallbearers of democracy? Are they defenders of the Constitution as written or super-legislators who make law from the bench? What did the Founders envision when they vested the "judicial Power" in "one supreme Court"?
