> its unfair to say every single direct manager doesn't care about their folks

That's not the claim being made, by my reading. The quote was, "Your managers, or your managers managers, or their managers don't care about you" -- which to me means, it's not clear exactly at what level, but at some point people stop caring about you as an individual. This may be at the direct manager level if you have a shitty manager. Or it may be much higher. But at some point up the chain it will become true if you're at a megacorp.
