This a thing that’s always been the case, but John Harris, who is a music writer doesn’t really understand why there are so many posh people in arts.
If we’re talking about *basic economics*, it helps to understand them. One of the biggest ones is supply and demand. Lots of people want to be in a rock band doing their own material, or writing novels, or to be an actor. It’s a pleasurable creative job that is high status. So, supply and demand means the average rewards for it are low. Yes, there’s Bono, JK Rowling and Tom Cruise, but they’re pretty much like lottery winners compared to the total number of players in the market. The mean average income for an author is £16,000. And that includes the authors with Scrooge McDuck swimming pools full of money like JK, Lee Child and the woman who does the 50 Shades books.
One of the effects of this is that people who don’t particularly need money can do it for longer than everyone else. If you’re rich enough, you can spend your whole life just going to rehearsals and trying to make it. Or just spend your life doing the sort of things that don’t make money, but are about producing art. So, everything else being equal, you’re going to get more posh kids doing it. That doesn’t mean it’s all posh kids, though. There’s going to be some genius kids from the working/middle class who will get through on superior talent, even without the advantages. Gary Barlow didn’t come from a posh house, but wrote A Million Love Songs when he was 15, which is better than most anyone can write their whole life.
