Townhall.com has published a fascinating article about household income inequality in America, based on a novel analysis of historical income data. Applying the mathematics of log-normal distributions to census data for the incomes of working and non-working individuals of both sexes, the authors found a way of simulating various household combinations that allows them to parse out the median incomes for each. By combining these results with the Gini index of income inequality, they conclude that rising household income inequality in America is due to the steady increase of single-person households.
The core of our civilization has always been the traditional family. As that crumbles, so does everything else.
