I think in a truly just society, the multiplier on the amount that a single individual could be compensated compared to his or her peers would have a hard cap. It would solve so many societal problems and also incentivize corporations to run more like collectives instead of fealties. Companies like Amazon, Google, and Apple would still exist, just as they do today; after all, their founders didn't get started out of the desire to make big bucks. But there wouldn't be any oligarchs on the other end of the pipe.
Not that it's likely to happen, of course! A person can dream...
