For 24 years of career I've met the grand total of _two_ such. Both got fired not even 6 months after I got in the company, too.
Who's naive here?
So now you and I both have come across such a manager. Why would you make the claim most engineer’s don’t come across such people?
Environments and local markets matter a huge amount.
I believe the better question here would be: why would the reverse be claimed at all? Many people in the USA, and a lot of them are over-represented here on HN, are privileged and this is not obvious to them, leading to cringe-worthy reactions like "just find a better company".
I guess I am barking up the wrong tree. I do dislike how over-represented certain perspectives are on HN. It's a very classic filter bubble, and the fact that it's about privileged people makes this even worse.
