Where,
You actually believe this idea about jobs being remunerated by ability, with the market efficiently allocating pay?! Have you been living in a cave since 2008?
Some of the thickest people I have ever met have been some relatively senior investment bankers. They did, in one sense, work hard, as in long hours and lots of meetings. However it is only a stressful job if you internalise stress from it. Yes, it is easy to be fired if you lose money, but most get re employed very quickly and, given what they can earn in a good year, a spell of unemployment is not a big deal.
The very high earning jobs are still mostly occupied by people from the right schools (private) whose parents secured them the right internships.
I imagine nursing is very stressful, shift work, risk of infection and, if you make a mistake. It could cost an actual life, not just money. And nurses are in short supply. But what do we do? Bring in less skilled workers from poor countries, economise on the standard of care, anything but let the ‘market’ do its job and raise the pay level...
I used to believe in unfettered capitalism when i was young, then I experienced the real world. Anyone who still believes in unfettered communism after the last 10 years is the equivalent of an ardent communist in the 1990s.
Neither systems are fit for purpose without a lot of tweaking.
