The existence of such people isn't (I don't think) in question, the question is how you organize a system so that their being in a position to run an organization isn't an unstable, non-equilibrium state.
It is not just bad luck or accident that businesses at scale, while they may temporarily be run by idealists of that or other stripes, either fail or end up run by people whose interests is in having the organization run as an optimized profit-returning (either directly or by increasing stock value so that investors can realize gains by liquidating some part of their holdings) machine above all else. It is the structural incentives of the system in which they operate.
