The Costs of Living Alone

> These efficiencies are an inherent feature of sharing costs with other people, but the barriers to living alone, for those who want to, would be much lower if housing (and health care, and education) weren’t so expensive.

One can argue that higher rates of divorce or singles raises prices for everybody, couples included. I think it is totally reasonable for governments to give benefits to couples and to "tax" people who live alone, in order to lower housing prices.
