So to answer your own question, when you are sick, need legal help, or stuck by the side of the road, do you comparison shop for best price or do you go to first available?
Right, and the comparison is usually not over price, but perceived quality. The best example for doctors is elective plastic surgery. Do you get a boob job from the cheapest or the best? The glut of expensive surgeons in the L.A. area indicates cost is not a major factor.
For lawyers it might be a lawsuit. Do you go with the cheapest lawyer? Most people go with who they think is most likely to win the case (or net the most money from the suit).

Unless you're also going to argue that the large number of expensive cars in LA "indicates that cost is not a major factor" for cars. (The same can be said for handbags.)
Never confuse what rich folk will pay for luxuries with real world prices.
