people need to escape from reality, porn helps with that
when there's a recession/depression people still need to escape from reality, generally even moreso than before
personally I don't think porn will ever die, it might morph into a different delivery model but I doubt it will ever go away, cos especially during the roughest times, people will always need to fantasize and seek to escape their day-to-day drudgery/misery/stress
besides.. it's cheaper to rent a porno (or subscribe to a paysite) and bang your chick on the couch (or the dining room, kitchen or wherever) than it is to go out to dinner and a movie
