Boards want the media to focus on the CEO because they are literally there to shield the board from accountability while “taking the brunt” of the bad PR - and also being a show piece for the company in good times
So, the real answer IMO is to change the law to implicate board members and investors directly as though they are officers equivalent with the CEO is setting corporate direction and incentives
Of course they have intentionally made the law such that any actions taken by the corporation, limit the liability of the board legally, while not taking the power away from the board to drive the direction and priorities and incentives of the corporation
The whole thing is an accountability shell game - Wherein a CEO is the whipping boy for whatever the board needs them to be the whipping boy for - and there’s a balance and ownership
The simplest way to put it is that the CEO is there to ensure that everything, the company does benefits investors primarily.
Until it is legally the case that corporate leadership must prioritize the benefits to labor above investors, nothing functionally is going to change.
If that big CEO paycheck came with some actual risks if you ignored ethics then maybe there would be fewer CEOs willing to do that.
