For starters, display good leadership traits like accountability, including to themselves. I'm worried the signal we're sending right now is that weak leadership traits are rewarded which incentivizes weak leaders.
These people's success is measured in dollars and little else so of course everything gets thrown under the bus if doing so will make more money.
Who are 'them'? The executives of these companies? Yes, of course some of them will act this way at least some of the time, and the question is what do we do, if we don't like it? We have some options, such as preferring candidates who favor stronger accountability and effective protection of whistle-blowers, and who are opposed to installing, as the political appointees heading the regulatory bodies such as the FAA, people to whom these executives can go to to get pressure applied to the professional regulators to back off their objections to what is going on. We can also support responsible investigative journalism by subscribing to it.
So, yeah, I'm not expecting things to improve anytime soon.
