I don't think there's a set-and-forget model solution.
But that's not what the US Constitution is, either. It was a legal framework and social contract that set up an elaborate system of checks and balances to prevent psychopaths from amassing too much political power. The democracy still running on that framework is a living, evolving thing, that has struggled to adapt with changing times, but it's done a pretty good job of keeping the psychos out of supreme ruling power (or at least keeping any one particular psycho from holding onto it very long) since 1787.
Meanwhile in the corporate world, we don't have that. Most private organizations are not even remotely democratic in nature. I think that's the core essence of what needs to change. And I think that's sort of what you're getting at by advocating open allocation and profit sharing.
Either that, or we need to at least strengthen the welfare state enough to decouple employment from basic livelihood, so that business failure doesn't impose the risk of homelessness/starvation, and most people aren't compelled to become MacLeod Losers, selling all their economic upside risk off in exchange for stable shelter, food, and medical care.
