Good ideas also take resources like time, free-space to think etc... many firms dont understand this. Moreover many firms believe the C-Suite are the almighty with the gods gift of great ideas.
Fair, I never said there wasn't risk involved with ownership. I even made sure to qualify when I said that people who own don't do labor, because often there is labor involved in ownership.
So I don't think it's a free lunch, it's more risk-for-lunch than labor-for-lunch. Maybe you could argue laborers are still risking their body or something, but I think the point might stand.
