As with everything, when the kit gets better, lighter and more functional the prices go up. Just imagine what the poor cyclist has to go through if he/she wants some of the best kit to peddle along on. $8,899.00 and that is just for the bicycle frame.

You can easily spend the same amount again for all the other parts.
