I wonder if the ever increasing average age of marriage (at least in the US) leads to more consumption. Imagine that most people get married right after high school graduation. Men certainly would have consumed within their means to attract women, but they would have been limited to what their parents gave them and what they could earn in after-school jobs. Would they still consume so much? Perhaps the "promiscuous" men would continue spending so they could attract additional mates?
