I can totally appreciate the desire for simplicity in work, and having a single objective number is about as simple as you can get.
But there's a difference between simplicity in jobs like flipping burgers vs finance, and that's power. If we work in a job that is both powerful AND simple (like many in tech & finance), it's likely many unintended externalities are being created.
Externalities, because they affect others, have strong political ramifications. So if you're working in a field with a lot of power, and you're having simple to nonexistent conversation about externalities, there's a good chance you're contributing to the problems you're trying to avoid discussing by virtue of wielding power blindly.
Perhaps those externalities would be better solved at their source of the workplace rather than let fester in the public sphere. This is a sort of 'ounce of prevention is worth a pound of cure' argument for why its important that workplaces engage in these discussions, and why the shareholder value maximization approach is too reductionist for corporate entities of any meaningful size or power.
