Should a person's personal wealth define their aesthetic experience?
Ordinary people can listen to great music like Mozart with relative ease - concerts are reasonably inexpensive, so the live experience is accessible to all and sundry. But art is obviously different - prints, photocopies, jpegs and the like don't convey the sheer drama and magic of great paintings - nothing beats an afternoon in a gallery soaking up the intimate experience with great art.

The painting above is "Prince Baltasar Carlos on horseback", painted in 1636 by Velasquez and valued at around $100 million. It is currently owned by the Duke of Westminster and he has full control over who sees the original - if he wants he can put it in a room and lock the door, he can choose to be the only person in the world to get up close to this masterpiece.
I think it's wrong that such great narratives of the human condition, the towering works of some of the greatest of our species, can be hidden away from humanity as a whole by people who happen to have more money than the rest of us.
