In Season 17 of “It’s Always Sunny in Philadelphia,” the Gang craves money and parasitic social privileges. That’s been plain since 2005. But they’re also human beings. They crave love, respect, conditional freedom, constant adulation, histrionic amounts of attention, non-stop gratification, and unfiltered, slaphappy eroticism. Produced by FX Productions.
