Comic Of The Day

Greg Mankiw posted this lovely "comic of the day." He called it "not completely fair." I'm non certain what he meant.

Perhaps it's inward postulate of a ameliorate caption. To endure fair to Keynesian economics, perchance the caption should continue,

"When you're done, about other one-half a box volition magically look on the wall." 

Maybe this is a proficient fourth dimension for a cartoon caption contest!
