There is no traditional economy or employment market in Antarctica. The people living there—scientists, technicians, cooks, pilots, doctors—are employees of their home countries' government agencies or research institutions (e.g., NSF/USAP for the USA, BAS for UK, AWI for Germany).
They receive salaries, housing, food, medical care, and logistics from their sponsoring organization. No one "makes money" locally; there are no shops, taxes, or commerce. All funding flows from national science budgets. The Antarctic Treaty prohibits mineral exploitation, preserving the continent solely for science and peace.
