Arnold’s post is this:
Married households with children were 40.3% of all US households in 1970; in 2012, that share had fallen by more than half to 19.6%. Interestingly, the share of households that were married without children has stayed at about 30%. Other Family Households, usually meaning single-parent families with children, has risen.
I am afraid that the number of households married to the state has soared.”
Another way to put this is that we are consuming more of potential gdp in the form of not being around those we do not wish to be around. This is a kind of extreme individualism in the personality-based sense, though not in the political sense.
