Ask HN: Why most founders are bad at taking care of their people?

In my career, I've come across a lot of founders who are bad at taking care of their people. I'm not talking about the occasional bad boss, but good people. I know a lot of founders who are genuinely good people, but when it comes to making a team, I see a systematic pattern of behavior that seems to be all too common.

Lack of encouragement, nitpicking, falsify one's feeling, damaging team spirit without knowing it, just to name a few. What are your opinions why good people turned into bad bosses? & how we should fix it?
