Earlier quoted context omitted.
I don't know any actuaries, but it always struck me as odd that the hardest working people in my last company were the actuaries. I mean these guys were on presumably amazing salaries, were some of the smartest people, could work at any related insurance/finance/whatever company (of which there are a LOT hq'd in Sydney) and had worse hours than most other teams. I just don't understand it.
Is it implausible that they might be getting amazing salaries because they are the hardest-working? (Why?)
Generally, rewards come from working smarter, not harder. Also, it's hard to make a lot of money purely on a wage. You usually need capital appreciation or other income streams for that.
