Not at all, first class is often not available on many flights, so it is the best that you can get. Generally these days Business class is often used as an overflow for Economy, airlines will overbook flights in economy, and if everybody turns up then they bump a few of the more frequent flyer's up into Biz class, providing there is room.
Its also a case of preferential treatment throughout the whole flying experience, from check in to landing you are given separate check in desks, a dedicated lounge with business orientated facilities and onboard you are given a much larger seat as well as an enhanced flying experience. More food of much better quality and a wider choice is what is most noticeable, normally there is at least one dedicated purser to attend solely to this section.
Airlines value the high end pax, its keeps them in business much more than a discounted economy fare does!
