writes "While tax laws, minimum wages, and patent extension are frequently blamed for the rising gap between "haves and have nots", an international economics study finds another simple factor behind income inequality. Marriage. As gender equality has improved in the professional workplace, paired incomes don't occur randomly. "Better educated people are increasingly more likely to marry other better-educated people while those with less formal schooling are more likely to choose a less well-educated partner." Using Census data, the (UPenn directed) researchers found that "across the board, the income gap between couples with relatively high and those with relatively low levels of education had widened substantially since 1960 relative to the average household income... the relative earnings of couples with high school degrees had fallen by 20 percentage points relative to the average while the household incomes of highly educated husbands and wives had increased by 43 points."
The Economist http://www.economist.com/news/... notes, " The economic incentive to marry your peers has increased. A woman with a graduate degree whose husband dropped out of high school in 1960 could still enjoy household income 40% above the national average; by 2005, such a couple would earn 8% below it." And in Slate, http://www.slate.com/articles/... Matthew Iglesias puts it in terms a nerd can related to. "She likes Doctor Who; I like Star Trek...But one thing about us is pretty similar: We both went to fancy colleges full of people with high SAT scores. And in that regard, we’re pretty typical." Perhaps "Natural Selection" is the best explanation for rising college tuition, and increasing student debt."Link to Original Source
