In many cases, it's literally not legal for them to do so.
For example, at the Federal level: https://en.wikipedia.org/wiki/General_Schedule_(US_civil_ser...
(These restrictions don't tend to apply to hiring one via a contractor at $250-500k/year, though. Sigh.)
If a defense contractor wants to pay someone that kind of money they generally have to pay the difference between what dcaa allows and that price out of their own overhead.
They very well may have to go that route, i.e. some greybeard independent contractor that can name their price. It's a very limited skillset and God knows this ain't the kind of work that gets the super talented motivated.
To hire someone who can do the job reasonably quick and well is really expensive no matter how you slice it. Consider it a 'job well done' if you can persuade them to:
a) Un-retire
and
b) Come out of said retirement to do actual work in the trenches again - as opposed to management.
In the private sector, these people have probably made the equivalent of GS-15 Step 10 for years if not decades. Good luck trying to convince them to jump back in for what is essentially a pay cut.
If you're making that kind of money, you have a lot better options than working on some ancient COBOL system that processes unemployment claims.
There's more to life than money and tech. I'm sure there are plenty of people who would be happy to work on a boring tech stack in helping to address possibly the largest public crisis many of us will see in our lifetimes vs. working with the new fad of the week in pursuit of selling ads marginally more efficiently.
Why spend the money and invest now for the future, when you can lean on people to donate their efforts in times of crisis?
First, no one said anything about donating effort...the scenario was getting paid a decent, if not quite FAANG, salary to work on an older tech stack. And sure, you _could_ take that approach. We tried it with pandemic preparation, let's see how that works out.
Just giving a frigging UBI for at least the duration of this crisis would solve all of these problems and work much better.
