Why are TV Commercials are More Expensive?

A location that cost $400 per day in the movies cost $600 in commercials. A location manager that has been looking for locations for 20 years in feature films charges double on a TV commercial. An extra in the Philippines cost $5. He walks in at a TV Commercial set and he gets $30. Same amount of work. Same location. Why the difference? For some reason ,location owners, PMs ,etc. all say-Well, commercials have bigger budgets. Bigger budgets?

Nothing has changed but the cost is more. In my experience ,advertising people are more picky but also more organized. They carefully choose who will be part of the cast, which location the shoot will be held at. They shoot at a place and leave making sure that everything is left exactly how it was found ,even cleaner- but why is everyone charging more once they know it's a TV commercial?

I wonder.
