I don't need no education...

The distinction that Postman makes in the last paragraph is that we often laugh and do not know what we are actually laughing at.  His solution for us is that we need to drop the entertainment and educate ourselves. Through entertaining ourselves, we are losing an understanding.  If we don't understand the problem, then how do you think that we will find a solution? In most cases, we will not.  By understanding the issue, we will be able to make decisions for ourselves and not just go with what everyone else thinks.  We were given free will for a reason.  Therefore, we need to educate ourselves so that we are not dependent on the world and we can rely on ourselves.
