The solution is in the element of taking the first step. That doesn't include mathematical analysis that says it's more cost effective to do nothing.
When major problems are clearly identified and NOTHING is done to protect anything but corporate profits, the controlling agency deserves to be burned at the stake - prior to lying about the reality.
Going to such issues as CRM and the crew-rest regulations, cost effectiveness has nothing to do with it. You may as well prohibit missed approaches.
Or, at least post a public notice that states that due to a change in the U.S. law, aircraft safety is not cost effective and let the passengers decide whether or not to get on a plane.
This nonsense of the USA maximizing aircraft operations at any cost - versus safety - is beyond ridiculous.
Rationalizing why human life has a dollar figure on it is in the league of Hitler's crowd - seriously. We're talking about transporting human beings, not robots.
