This is a nice idea but the problem isn't the individuals in the system but the system itself. As long as shareholder value/profit is the only factor companies consider this is the end result you will get.

Management is just making decisions based on what the companies value and companies are just valuing what their shareholders value which is more money for the shareholders.

The best way to fix it would be to reform the stock market system so that companies aren't beholden to uninvolved third parties looking to make a quick buck. Only active employees should own stock in companies and sit on company boards.

This would also require reforming the retirement system so retirement money isn't just dumped into the stock market. It needs to instead go somewhere safe and just sit. Retirement funds being in the stock market creates a huge inflationary feedback loop by demanding constant increases in profits which cause companies to raise prices which causes retirement funds to need to be bigger which causes them to demand more profit increases.
