It was Mises's fundamental point about the cultural critique of capitalism that capitalism makes more of everything available to the consumer. That means more trashy novels and rotten music, but it also means more great literature and high-level music, all of which is accessible as never before.
But today, cultural entrepreneurs are seriously inhibited in their innovations by high taxes, regulations, and mandated benefits. This produces fewer attempts to improve our world than there would otherwise be. Some markets are hobbled to the point of near inaction, such as the education market, and others are less vibrant than they would otherwise be.
So what we need is not the overthrow of private property but more freedom for cultural entrepreneurship, and more individual initiative to do more than complain that the world is not conforming to your own values. The next time someone complains about what the market is doing to the culture, ask that person what he or she has done to enter the market and make a difference. And ask what that person has done to make the world freer for those who seek to make the world a more beautiful place.
