alt Hacker NewsI genuinely need to see what data you're citing with this statement. Until recently, I worked in education and often worked with urban schools. Starting salaries of 55-60k/year living in a major metropolitan area is not what I would call economically privileged.
The average CPS salary is somewhere around $75k, with 10+ weeks of vacation, but that undercounts it dramatically because CPS teachers get defined-benefit pension plans and often earn tens of thousands in additional cash comp for extracurricular work, and that's before what happens when you get a masters.
