$150k is a lower-estimate for this family, they probably beat the $165k to qualify for top 5% household incomes in the country.
High amount of autonomy in their work, advanced degrees (beyond college: masters degree plus continuing education), significantly higher wages than everyone else... yeah, upper-middle class.
Ok, I think we keep talking past each other, because to me, upper middle class is just a subset of middle class. I don't think it's wrong for people who belong to it to describe themselves as middle class, because if you're in the upper middle class, you have a lot more in common with the rest of the middle class, than you have with the upper class.
If that family isn't middle class, what are they then?
