Paying more for a job already designed to attract terrible people will still attract the same terrible people, it will just make them richer. Again, see police departments.

You can see a different sort of example in teaching: teachers put up with terrible pay for a long time, but now they're quitting in droves because of terrible work conditions and lack of emotional fulfillment.

You have to change the nature of the job from something designed around theater and blustering to something actually useful. The pay is never the problem, it's that the jobs are bullshit. Although once the jobs are no longer bullshit, we should probably pay them better.
