I'm try to figure out why FedEx isn't blowing UPS out of the water in profit margins since 1. FedEx Express starting pay is way less than UPS (like $5/hr less to start). 2. FedEx Express takes anywhere from 10 to 20 years to top out their drivers, while UPS does it in less than 4 yrs. Salaries are usually the biggest expense for a company. 3. FedEx Ground uses a subcontractor model where FedEx doesn't pay any benefits or retirement. FedEx should be making way more money. I understand FDX has a fleet of aircraft, but so does UPS. What am I not taking into consideration? I just don't get it.
