Not equally (where did I say that?) but put frankly it depends how much risk.
Everything is a trade-off, and actually what we usually aim to do as society is to manage acceptable and balanced levels of risk rather than use safety as the single-lens to make decision. As an example, the design of cars would be very different if they were designed only with safety in mind, and if automakers pursued this goal ignoring factors such as speed, comfort and price point (or indeed, competitive pressures).
It's also worth noting that the "efficiency" in my post actually came from the stated goals of the FAA.
