I think game Console is a strong indicator. SNES and PS1 thru PS5 are strongly tied to the middle class. Xbox is prole. High prole in some cases but still prole.

Acing OCI/OCR/Match Day I.e. being Recruited on the basis of Clique/Class (and GPA). If you have to apply to 5000k jobs and had to Waitress or something during the Great Recession (caused by Gen x malfeasance btw) then you’re probably prole.

7 figure household net worth (not 8)

NOT being Gen X

JMO, YMMV

Upper middle: Paying for kids’ college like it’s nbd and private school too. Also coming back to Consoles, 3DO is inexorably linked to the UMC
