They are the minority with a VERY small staff, compared to most others. (Also HRT engineers work a lot, not leasurely 40 hours per week)

Pointing to extreme outliers is not giving your opinion much credence. Because I can point to some people who work in crypto, that earn $600k+ without breaking a sweat - in Singapore with Singaporean taxes(which blows HRT salaries with US taxes out of the water)
