> You put more effort, you take responsibility for stupid people's decisions, and then you get a disproportionately small reward
On that I disagree. Managers might have to take responsibility for bad decisions, sure, but get a disproportionately larger reward than those under them. It's certainly less stressful at the bottom of the ladder, but don't expect to get much praise or monetary reward, and you're the first to go as soon as something goes wrong. There's a reason why late-stage companies are full of middle managers, and few people actually doing the work.
