I would frame the question differently. How much does it cost to set up and maintain a company that develops state of the art racing bicycles, sponsors racers, markets their products at events around the world, has worldwide distributors, etc. Bicycles are not much different that many other manufactured goods in that the cost of the product itself is just a part of what your paying for.
If you believe a product is superior to others, then you have to expect to pay for the infrastructure that went into its development.
