Look at the divorce rate vs our parents' generation. Also, look at the population pyramid: there are 20 million more 0-24 year olds than 25-44 (2010 Census). That means we are bottom heavy and catering to the youth (prevalence of video games, Twilight/teen movies). Also the delay of education in conjunction with fears of marriage have transformed the 30's into the new 20's generation.
damn, that explains the constant sharing and checking in nonsense to tell everyone where you're spending money
