My parents had no arts education whatsoever they still enjoyed the theatre and visited galaries etc. They also enjoyed bingo nights at the local working men's club and my dad loved football. The division of pastimes into good culture and bad culture is a middle clsss projection which has dominated society and set up barriers.
I knew someone was going to say this, which is why I pointed out that football and bingo were simply signifiers for 'not Cultural' pursuits (and that is not to say that they are not small-c cultural, before that is pointed out, too).
The point is not that any group is unable to enjoy any type of entertainment - of course that is simplistic and idiotic. However, it is equally idiotic not to acknowledge that a lot of people believe that certain forms of Art are 'not for them'.
Many years ago I taught O level English to disadvantaged students in an FE college. The biggest problem was persuading them that Shakespeare was not for 'swots' and 'posh people'. Once we'd got over that hurdle they were mostly very receptive, and the results were better than expected.
If Arts are not taught at university, and are seen as inferior subjects at school, the attitude that they are 'for others' will continue, and the vicious circle of 'there is no point in putting an Arts Centre here - build a pub with a vast TV screen instead' will be perpetuated.
I don't know how old your parents would be, but it is also the case that in the past, people didn't have the choice of TV and YouTube entertainment that is available nowadays, so were maybe more likely to go to theatres, which had a wide range of plays on offer - designed to appeal to all tastes. They were also cheaper than now.
