I have quite a few creative ideas, but am too tired to write them down rn. I’ll go the easy, lazy way (and write about more legislation ideas tomorrow):
Proportional representation like Germany. In every election, the voter votes for an individual and a party. The individual is chosen to represent the riding through STAR voting (my version). After all MPs are elected, to ensure proportional representation according to the party votes (the second vote that voters cast), individuals from party lists are put into parliament.
This way, we get riding representation and party representation.
In most corporations, the only thing that shareholders really do is vote in relation to who the directors are. The directors and officers are generally the ones who actually do things.
The directors are often also in charge of share sales and transfers. In corporations not in the stock market, you often can’t sell, redeem, gift, or otherwise get rid of you shares whenever you feel like it.
Officers are also appointed by directors, not by shareholders, so that could be another step removed from having agency over what’s happening.
Many CEOs have shares as part of their compensation package, as do many other members of the C-suite. Regardless, by making voting shareholders liable for all cause penalties, their selection of leadership roles would necessarily change. That would include lawsuits, fines, environmental penalties, HR violations, civic wear and tear, back taxes, etc.
Most shareholders has no control over the actions of the President or CEO, or even have any power to decide on who any of the officers of the corporation even are.
In your hypothetical senario, you should consider the board of directors or maybe even the ISC.
