Just a quick note for something I hope to visualize eventually. The political middle refers to where the media articles about families and money/income/tax matters tend to put generic examples of married parents. It’s not the median (101k/yr), or the average (130k/yr) or even the middle 50% of married parents (as of 2018, 60k-165k for the 25th through 75th percentiles).
It’s typically a low number of 50-60k/yr. Sometimes it’s higher, but generally a number along those lines is presented as the dead midpoint even if numbers like the above, closer to true middle numbers are thrown into a profile of 4-6 “middle class families”.
