A middle man doesn't necessarily increase prices. If you want to letter a package from the east coast to the west coast, do you forgo the USPS stamp simply on principal they are the middle man and thus increases your cost? I can think of a handful of questions that need to be answered besides just saying "middle man bad". What's the cost of delivering dozens of vehicles from the plant to a dealership vs delivering one off vehicles to a house? Or the cost of an OEM having their own employees distributed to answer questions on a vehicle. GM has more than 4000 dealerships...would sales decrease because it would be less accessible to customers to see, test drive and service vehicles? I don't believe the current dealership model of huge lots, tens of employees is efficient. But I'm not so certain an OEM handling everything themselves is optimal.
