I think the working class have been screwed out of a genuine source of lifelong pleasure by the education received (like my own - until college/Uni.). Add to this the relentless hostility toward modern art over the decades by the tabloid press, and a certain section of society are practically bullied into a skewed view of the world.
One of the (many) reasons it's so hard for working class artists to get anywhere in the art world, is the lack of network to begin with, the lack of support, time and money to able to dedicate themselves, which is not the case for the middle/upper class. I would argue that the people who could benefit the most from actively pursuing an interest in culture is the working class, and yet, it seems largely viewed as dispensable.
