Classical Arts like the Symphony, Opera, Ballet, and Plays are all things closely associated with am open and cultured society.   They are also intimately tied to freedom of expression.   They also owe much to Democracy, as the world's first Democracy, the city state of Athens, made huge advances in developing the arts.   They laid the foundation for Western Civilization.

If you don't like these things, you could always move to a country where the arts are banned.   For example, simply move to the new Islamic Caliphate that ISIS has created in Syria and Iraq.   I can assure you that things such as plays, opera, ballet, symphony, etc do not exist there.   In fact, ISIS has beaten and tortured many people just for playing musical instruments.

Here is a video of people explaining why the arts are important to society.
