$180k is not "working class," period. I don't make $180k and I live in Seattle working in a tech-adjacent field. You claiming that it is is like saying a 14 year old is almost 15 which is almost legal driving age and basically an adult in terms of responsibility, so it's pretty much the age of the majority at 18.
I went to a big state school that was respectable but not Princeton. I still wouldn't say most students there were from the "working class" by the common definition: https://en.wikipedia.org/wiki/Working_class
> The working class (or labouring class) comprises those engaged in waged or salaried labour, especially in manual-labour occupations and industrial work.
How many Princeton kids had parents who worked construction? Plumbing, drywalling, tar roofing? I'll guess: very few.
