I think the line "in all our decadence people die" is pointing out that we use our time and money to look more sexually appealing (for instance, by shaving our legs and armpits) when there are other people who are starving in the street. With labor conditions the way they are in third world countries, people's deaths could even be the direct result of our decadence if we buy cosmetics from companies who have outsourced labor and not bothered to not treat their employees like shit.
