The only way the corporate executives of a corporation will ever pay attention to pleas and heartfelt advice from employees - even high-level well-trusted long-term employees - is if those employees are the controlling shareholders who have real voting power over the makeup of the corporate board.

Democratization of corporations - tiered somehow, as you probably want experienced senior engineers to have somewhat more votes than a new hire with six months on the job, so not 'one-person-one-vote' - would probably go a long way towards improving how corporations act in reality. Yes, this would mean that shareholders lose control of the makeup of the corporate board - which is a very good idea, capital should always take a backseat to labor, as without labor, capital can't do that much.
