I agree with Ihatefish. The reasons to do all these things should be because you're curious and interested and because they enhance your life, not to give you "cultural capital" (which is not what the OP thought it was anyway).
To be fair to the OP I don't think she meant it to sound as wanky as it did and she's had a right pasting on here which was probably a bit harsh.
But its an interesting one to unpick: I do all of these activities when I can and as far as time and budget allows, alongside a ton of other less culturally edifying stuff (not as often as I'd like) and I do them because I like them.
For me, if you do this stuff because you like it its a good thing, if you're doing it out of some sense of middle-class keepy-uppy or to help your children flourish at their private school its a completely different ballgame. I appreciate if you haven't had access to these things as a child then the premium on them is higher and I don't hold it against people who want to do it for this reason. But I still find it depressing and nauseating that these things are seen as stealth class signifiers.
It would be nice if the class signifiers could be taken out of this mix so people could enjoy going to the theatre or bingeing on Netflix as totally equivalent passtimes without all this baggage and judgement. Unfortunately, as long as "the arts" is seen as the preserve of the "cultured class" this isn't going to change.
I think we could do ourselves a favour by getting rid of the the phrase "the arts". It has a built-in set of assumptions about what defines "arts" (fine art and photography, opera and classical music, theatre not musicals highbrow literature etc) which is totally linked to class and money and no longer useful in the digital age anyway.
