Nurses form the backbone of healthcare. Treat them as such.
Edit: To those downvoting me, talk to a real nurse and I bet you wouldn't take twice the pay to do half the work they have to deal with.
There's a good argument to say that sufficiently aggregated marketplaces can launder price collusion, and if we were in such an aggregated marketplace then you could make that argument. But we're not in that situation right now.
The 'Edit:' is even more confusing. If I talk to someone in a profession and I wouldn't take twice the pay they receive to do half the work they do then they deserve higher wages? But that list is huge. Congressmen, Senators, many CEOs, Wagner-group mercenaries, ICE officers, drone pilots. In fact, almost every profession has this 4x effective slippage you're talking about.
One movie that made me change my perspective on nursing as a field was the Swiss movie Late Shift. It really opened my eyes to what nurses have to deal with. Yes the US might be different in having lower patient to nurse ratios but at the end of the day I think it's still applicable.
I still think their monetary compensation should be provided by market valuation of the utility of the work they do.
