Again like doctors, nurse wages aren’t a major factor in the discrepancy between US healthcare costs and elsewhere. They are a factor, in a death by a thousand cuts situation.

In a source posted by another commenter, their wages are accountable for 5% of the difference.

I also don’t think it’s accurate to say regulations are what’s prohibiting an increase in nurses. They don’t have a government imposed mechanism like residency funding that creates a bottleneck like the one in medical training.

We have a nurse shortage because we have an aging population increasing demand, it’s a tough job, and people are leaving the profession.
