"Sysadmin" seems the most readily comparable title in IT, going from "I push software to Windows PCs" to "I manage supercomputer clusters."
And the answer to that is "how much is Google worth?" If your business relies on the efforts of software engineers to design and build your primary products, they should have the primary equity in the company. So no, even Google developers aren't paid nearly enough...and they're certainly overworked, regardless of how much they make.
The average tenure at Google is 4 years. This means that most current Google's have joined when the company was already at sky high valuation. They made incremental improvements to the product line. But arguing that they should own the majority of the shares is just ridiculous. Think about it: if google had made no new development in the last 4 years, how much would it still be worth ? The answer is: not as much as today, but probably quite a lot.
Current employees thus deserve a part of the pie, as they are the one tending for it. But when they joined the pie was already very nice, and they had 0 impact on that. Not with their work nor their investment, so they can't claim that part for themselves.
While $100K/year is not the norm throughout the country, it is normal in my city (non-SV). Travel nurses made a lot more during COVID.
From my conversations, pay is not the reason they are considering leaving. Working conditions are.
What you need to realize is that nursing salaries in the US are NOT uniform. From what I've seen in past discussions about it is they range anywhere from $20/hr -> $100k/year. The $100k/year are usually achieved only in cities and generally only by travel nurses.
The majority of nurses, that I've seen, are clocking in at 50->60k yearly salary.
Sort of like saying "Oh, that google dev makes $300k a year. How much more do devs in the US need?"
