Mickey D's, Burger King and Taco Bell continue to thrive. Nevertheless, The French Laundry is full every night. A segment of the population appreciates great food (and can afford to pay for it). Ditto for photography.
I'm not just talking about French Laundry. I'm talking about home cooked food also. There was a Documentary about men looking at retouched women in magazines called "Wet Dreams and False Images" by Jesse Epstein.
