In some places they may be highly paid. In many, they are not. I know this because of close family who have worked as managers of multiple hospitals and hospice that have extremely uneven pay scales even in a single region. You might even assert that the people with less pay have more/sufficient staffing on hand but you would be wrong. The amount of WTF/hospital in the US never ceases to surprise me.
That may be the case in the US, but not in Germany and Austria. Nurses are paid pretty bad, and, surprise surprise, they're having problems finding people to choose that career.
Yeah there's this huge demand, for which they blame blame the nurses "ungrateful snobs" or get upset that immigrants are hired "taking away our jobs" or...
I'm actually curious in what parts of world anyone would genuinely consider nurses to be "highly paid". The hourly rates for some types of nursing work can be quite decent, but still markedly less than what virtually anyone in IT with similar levels of experience would expect to receive. And it's often sufficiently physically draining that it's not feasible for most to work 40-50 hours a week.
