Tripod Costs

Has anybody wondered why it costs for a tripod, head and a few plates almost the same price you pay for a D70 and lens?
I mean what on earth are you paying for. Atleast with a D70 I can see the technical expertise that went into it to produce it. All I see in a Gitzo or a Markins ballhead is a few machined peices of material that would take sod all time to make.
I always thought RC Planes and Helicopters were expensive and an old mans hobby when you're retired. Man, I could of bought 2 RC Planes for the amount I've spent on camera gear.
