Creating videos of lean, fit people showing off their bodies does not attract an audience of lean, fit, healthy people —quite the contrary, it attracts an audience of people who see in that performance something they lack.
They only yearn for what they lack: so it is that highly intellectual content attracts an audience even more mindless than mindless entertainment.
I realize how difficult this is to believe.
You cannot raise the intellectual or moral caliber of your audience by raising yourself up: you can only attract an even lower audience that enjoys gawking at you from a greater distance. Their very inferiority will make you seem exotic in their eyes.
