Perhaps WLD but culture (singular) implies homogeneity, a monolithic and easily accessed national default which infers stability in a range of key signifiers. I don't think we have that. We have a situation where skateboarders are on an equal cultural footing to pianists which are vying with experimental video makers and football shirt collectors.
I'm not attributing value to the situation, simply remarking on what I observe.
Actually, there is a prejudice against traditional forms and groups and anyone trying to attain money for artistic projects from the larger sources will find diversity, inclusion, ethnicity, etc., are terms that free up cash more readily than continuity and permanence.

It doesn't make Daily Mail type steam emerge from my ears because all sorts of groups have hogged creative resources over the years, financial and human and most were mainstream, male and white.
