Why do you think "merit" and "works well with the employees I already have" are unrelated?

I suspect that's often true, but certainly not universal.
For example, allegedly, some people want slaves and want to lord themselves over their slaves. So they would never hire people like themselves, SES wise; they would only hire people where it was clear (in their own minds) that there was SES or other status daylight between themselves and their "underlings" So I'm not sure there's a universal law of hiring. I agree that "hiring someone like me" is a common -- but not universal -- pattern.
(Oddly enough, in the USA in 2026, I think you'll find that white males are the _least likely_ to use the "someone like me" hiring strategy - if for no other reason than decades of targeted enforcement against that that group for appearing to employ that strategy. Eg the Indian preference for hiring Indians, or the female preference for hiring females, is stronger than the white-male preference for hiring white-males. Maybe not in terms of hidden preferences, but in terms of actual hiring outcomes, yes, that's what the data will show)
Back to the non-universality of hiring strategies: A friend of mine with a tech business intentionally tries to hire mid-field performers. He doesn't want a rapid climber, because he cannot afford to keep them on staff once they understand what they are worth. He wants mid-field performers who are going to do solid, reliable work, and be content to work for him for a long time. So he doesn't hire on "merit" - he hires for "good enough, low turnover"
Other businesses have other strategies.
