In an interview with Parc Media, Roger Waters said
By the time I was 15, I was chairman of the young socialists in Cambridge, not for long because really I didn’t give a *** and I didn’t have the stamina either, I hate committee meetings.
I would be happy to be called a socialist if I thought that adjective was appended to people who cared about community and about social welfare. So if a socialist is somebody who believes in the 1948 universal declaration of human rights which is a socialist document because it believes in our right to food and shelter and health care and life and liberty? Well then yes, I am because that’s what I believe in so absolutely and I do. Can you believe in Marxism? Well it’s not really an ideology but it is a description of economic systems that has a great deal of truth in it.
