Congress is doing a full-on impersonation
of Columbus, dragging us very confidently and at great expense in the
opposite of the direction of where we actually want to go, so that we
wind up somewhere that has no gold.
But most of us do not have those resources. We have to settle for a small gesture, like throwing a Columbus Day party where bad directions result in our going to the wrong house and accidentally giving the occupant an incurable wasting disease. And tomatoes!
Alternatively, you can claim to discover something that has been around
for years and was getting on perfectly well until you showed up and
ruined things, say by casting an elderly lady in a big-budget movie.
