The Literal (and Semiotic) Seuss.

The original Buzzfeed post from whence these came seems to have been airlocked, but the images have survived at LinkMachineGo and elsewhere: What Dr. Seuss Books Are Really About.

Or for a longer but equally goofy answer, see Louis Menand in The New Yorker, circa 2002: “The Cat in the Hat was a Cold War invention. His value as an analyst of the psychology of his time…is readily appreciated: transgression and hypocrisy are the principal themes of his little story. But he also stands in an intimate and paradoxical relation to national-security policy. He was both its creature and its nemesis — the unraveller of the very culture that produced him and that made him a star.”
