I completely agree.
I certainly would accept more pay. But I wouldn't switch jobs just to get it. There are several reasons, most importantly that interesting jobs in my niche are scarce. So my employer has a resource that is perhaps scarcer than myself!. Second (and this is the part where it becomes self-fulfilling), because there are no super high salaries, I'm close to a kind of ceiling. I'm not sure what that ceiling is and you could always be lucky and find some extremely well paying job, but let's say that for a job I'd be willing to do, the ceiling is within 50% more than I'm currently making.
If marginal taxes are 50% (at least), then that's a net 25% pay rise. It's basically $1500 more a month net, and it would require me to make probably several job switches. It's certainly not insignificant, but it's just not significant enough. Had there been jobs across the street paying 3x what I do, then certainly I'd start chasing more money. But I value my 6-8w holidays, I can already afford to travel etc. I'm comfortable.
