Is high quality not a market product?

Ludwig von Mises is (or was) one of the greatest minds of our known existence. I don't disagree with the man in any areas. Everything he has written and I have read makes perfect sense to me. So far, with only one exception.

Mises writes:

One of the great problems of capitalistic civilization is how to make high quality achievements possible in a social environment in which the "regular fellow" is supreme.

How is this a problem? It is basic knowledge that in a rich society (thereby capitalistic), more people can afford more expensive luxury than in a poor society. The higher arts are a form of luxury. Therefore, the "normal" individual in a capitalistic society is relatively rich and can afford to buy more expensive products AND arts than the one stuck in socialism and other forms of economically destructive systems.

Mises's worries might be explained by the fact that relatively fewer will indulge in the higher classic arts compared to the normal when mass-production takes over from the historically more common home-craftsman-ship. But relativity is a false measurement for popularity. Ask a 1000 persons about their favorite book and only a percent or so will say the same title. But that doesn't mean there is a lack of taste among the masses. It only means the competition for the "best" is hard, and that a massive number of excellent books is competing for the title.
