So I've come to develop a nuanced opinion on this.

I used to fully believe what you said, on the grounds that willingness and ability to negotiate have no bearing on how valuable the employee will be (at least for engineering jobs - it could be different for something like sales where dealmaking ability actually matters).

However, one counterpoint I've come to realize is that if an employee doesn't value higher salary that much, it's a waste of money to pay them more. Thus, by only paying higher salaries that put time and effort into arguing for higher salaries, you make sure to only spend that money on the employees that will actually value all the extra money you're throwing at them.
