If I had to choose between common good and shareholder value all else being equal, I'd choose common good every time.

We should be suspicious of games that favor shareholder value over common good and repair them. Of course this is harder than it sounds, but letting the person with the most money in a Monopoly game also set the rules is absurd and and obviously wrong. Wrong even without having a consensus reality on what "common good" entails and this is important.

The "capital game" should serve us, rather than us serving it. A fatalistic lack of imagination is no longer an option. When we're more afraid of unintended consequences than accepting that we have a responsibility to the current consequences, our current consequences look rather intended.
