If the individual full-time median is $60k and married household $119k does that basically mean that the median married couple has both spouses working full-time?
Or it has one high-earning spouse and one at home making little to no money.
But that would imply that being married increases your income.
...or that increasing your income causes you to be seen as a more appealing partner and therefore more likely to get married.
It is absolutely the case that marriage rates are declining amongst the less-educated and lower income, while marriage rates among the college educated and affluent are stable and high.
The kinds of people who earn higher incomes are more likely to get married. Then the woman (obligatory discalimer: typically, not all cases ofc ofc) starts to work and earn less if/when the couple has kids, whether that's down-shifting, switching to a different (more flexible) career, or staying at home entirely.

Re: the OP (just being pedantic), I would quibble with the statement that people who make $60k are "squarely middle class" if the median income is $80k. To my mind, "middle class" definitionally means "around median income," so $60k would be on the lower edge of middle class. I think it literally is around the lower edge of the median income quintile, so it's definitely middle class, just maybe not
squarely.
It is distressing to feel below average, so even though $60k is enough to live comfortably on, I can understand why people earning $60k would feel displeased about their income.
And further pedantry about these labels: there's this euphemistic thing about American class where everyone above middle class calls themself "upper middle class" straight up to the top 1%. No one will acknowledge they are straight up upper-class income.
The fourth quintile of household income, which is what I'd call "upper-middle class" is from ~$94k to $153k (slightly dated numbers, from 2022). So households above ~$153k are in the very top income quintile, and as far I'm concerned, should not be calling themselves "upper middle class" anymore.
I guess part of the fuzzy line here is that lots of people earning these kinds of incomes are in the richest cities, where they might still be in the fourth quintile
locally, even though they're in the top quintile nationally. One could be nationally rich but only NYC "upper middle class," but still, living in one of these high opportunity cities is a consumption choice that is an affordance of that high income.
