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.
