Basically, in 1919, Henry Ford sought to reinvest the Ford Motor Company’s profits into raising employee wages and expanding hiring, arguing that sharing success with workers would strengthen the economy and the company’s long-term prospects. However, minority shareholders John and Horace Dodge (who also ran their own competing auto company) sued Ford, claiming that his actions violated the fiduciary duty to maximize profits for shareholders.
The Michigan Supreme Court ruled in favor of the Dodges, declaring that a corporation’s primary obligation was to serve the financial interests of its shareholders and not broader social goals or even the well-being of its employees. This decision established a legal precedent that continues to shape corporate law even today and reinforcing the doctrine of "shareholder primacy" and limiting the ability of companies to prioritize stakeholders (like workers or communities) over investor returns.
It's been downhill for employees since.
