Here I think it's a little different. First, you can't just mint new nurses. That takes time. Second, a lot of nurses have left the profession (or at least specialties like ER and ICU) because of years of stress dealing with the fallout of the pandemic.

Nurses were at one point and in some locations quite literally choosing who gets to live and die. If you don't think that puts stress on someone, combined with being overworked, I'm not sure what to tell you. So it's not just an issue of money to lure them back, particularly when (later on) so much of this death was entirely self-inflicted (ie people choosing not to be unvaccinated).
