> Average pay for manufacturing engineers is about $78k
This is more on par with pay for (top) programmers or engineers that I know of. In South Africa, actuaries get paid much more than programmers. From what I have seen on HN, US based programmers (in top-ish companies) get paid actuarial salaries. As a mathematician, I have a lot to say about actuaries, but alas, that is for another day.
Maybe someone more knowledgeable can clarify this. Median pay at tech companies is sometimes > $100k annually. In my view as a not-a-US-citizen, that is a lot of money.
