You can fire half the commercial pilots, and planes will continue to fly without a hitch. Why have two pilots, when one will do. Trucks have one driver and work just fine.
Eventually some planes will crash, but it's ok as long as it happens after effective management gets their bonus and moves on to optimise another company.
