Joking aside, and not meaning any disrespect to those who have been lucky enough to earn enough following their dream...
I did a lot of music when young and I toyed with the idea of a performing career. I then thought I could be an accountant in an opera house or something. But when I qualified and looked around I found I couldn't pay the rent that way.
Some of the very confident and wealthy kids at oxford with me (remember we are talking about the early 1980s before all the access efforts) went off to be violin dealers, Persian carpet dealers, do a bit of singing, etc. In those cases it was underpinned by daddy paying rent and very soon by a rich boyfriend. I do of course know a lot of ppl who have had careers singing or performing and teaching who are not like that, they are properly and endearingly hard up. But they also get by as a family with someone else doing a more mundane job which pays the rent. And I know a lot of lovely creative fun women who say, "well of course I have no earning power at all" and see no way forward from that. In some cases the family is broke and they are very frustrated,
I thought this was a generation thing, because I was told that a creative career was now much more of an option, with the rise of the Internet, film, etc. I thought that ppl doing A levels in art and humanities degrees would find higher paid work. But it doesn't seem to be happening yet to DC's cohort. They are all out there, but doing non-graduate jobs, or in some cases not really finding a proper job at all. Whereas the kids who did science and maths are on the whole not doing non-graduate jobs. And the very musical kids are out there trying for performing careers with not much of a backup in terms of saleable skills.
Which slightly worries me about girls a level choices because I think you can follow a pleasant route at school and Uni doing what you enjoy, and then find that as a mother it is hard to identify a smart career option, which allows you to earn well in minimum time and minimum commute while spending whatever time you want with your kids.
I sort of think that anyone who might to work part time and/or have time as a SAHM should seriously consider doing A level maths and other sought after subjects to protect their future earning power....
