I'm suggesting that in the long run, any organization that is hierarchically "overseen" by humans with outsize power compared to the employees (aka a "Board" of special people that are better and smarter and more politically well placed than disposable employees), will inevitably exploit the structure for selfish gain with a probability of 1.

The STRUCTURE is wrong is the point.

The entire concept is built around would-be-aristocrats (Board) coercing the management and employees into allocating property (Money) based on their whim with no accountability or democratic function. It is built to exploit.

Instead they should organize as a non-stock cooperative so that is effectively impossible to exploit. That's the actual answer.
