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.
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.
