That doesn't answer my question at all. Saying that the income of a single-parent family is lower does not remotely answer the question of "What is the magnitude of the effect of single-parent homes on the size of the middle class?" I actually went and looked up the tables in the census: https://www.census.gov/data/tables/time-series/demo/families/children.html https://www.census.gov/data/tables/time-series/demo/families... We have the same percentage of single parent families now as in 1995 (29%). That's over 20 years, the number has barely budged. So how does your answer relate to the question of the decline of the middle class since then?
