Afford. 1. To have the money for.
The guy in the cartoon says sarcastically that he is more worried about covering his costs (affording toilet paper) than self-fulfillment. :-)
Afford also means 2. to be able to do (something) without causing oneself trouble or difficulty, e.g. I can't afford to be rude to my boss (because he or she might fire me, not give me a salary rise, etc.).
The Youtube video campaigning for the (now approved) US health care reform uses the word in both senses (the people 1. don't have the resources for private treatment and 2. if they don't have it their health will suffer).
