> If anything I see selection for wealth: the samples in one of the bigger studies selected from “the 15 best STEM graduate training programmed”, which is broadly a proxy for wealth. Not everything is about wealth. STEM graduate school doesn't select for wealth at all. Undergraduate admissions sometimes do, but essentially zero of the wealth-based admits major in STEM. In fact in my experience the effect is the exact opposite of what you say: STEM takes in whoever can do the work, regardless of wealth, and helps produce new wealth. In every institution I've been in, STEM people had the lowest average family wealth by far.
