You've totally lost me there.
I've had good managers before, I'm not sure why you're saying I haven't, or how that's related to my central claim.
Also "WYSIATI" is a misdirection. You could suggest that to anybody in any argument (I could suggest it to you now). But without providing any evidence of what those unseen factors are it's of no probative value.
I don't think you're trying to understand my point in good faith anymore so I'll leave it here.
