If I'm allowed to wish big:
I wish I had something like Wonder Woman's lasso, forcing people to tell the truth. Imagine if dozens of evildoers in positions of undeserved privilege and authority suddenly went on television and confessed their crimes! Before they could recover from the spell, I would make sure they turned over proof, so they couldn't pretend afterwards that their confessions WEREN'T the truth. Then, millions of honest people, who honestly differed about who was right on various issues, would enjoy far more certainty about which side to take in any question.
