While true, ~30 percent of households in the US are single-person (see https://www.statista.com/statistics/242189/disitribution-of-...). And a number of others are single-parent. The parent specifically talked about a couple's combined incomes.

Looking at https://www.census.gov/data/tables/time-series/demo/income-p... (the "Married-Couple Families" section), the first data set ("All Races"), the numbers I see for median household income, by age, are:

25-29: $76.5k 30-34: $92k

30-34 is stretching the definitions of a "young couple", of course. I'd love numbers for 20-25, but this data set lumps in 15-24 all together, though the set of married couples under 20 is presumably pretty small.

$76k is still not $100k, of course.
