Art is directly related to reality and it should talk about its problems: politics, the environment, possible wars and social problems.
Artists are people with a certain status in society. People admire them for their unusual vision of this world. People want to follow their idols, whether it's a performer or an artist. Therefore, artists are those people who can "make" people think, give food for thought. Artists can change the vector of development, give the first impetus. So why not to do it, since art is such a powerful tool of influence?
