Well, no, that's clearly not the case. It's always possible to improve the safety of a plane by spending more money. Airlines could do a 72-hour safety review of every plane after every flight. Planes could have 7 copies of every system/sensor instead of 3. We could stick 6 pilots up in the cockpit in case the first 5 have simultaneous mid-air heart attacks. Deciding to shift the needle from "safety" toward "economic feasibility" is very often the correct thing to do, and vice versa.
