I think what Louise does not appreciate is that
1.The arts are an industry, and one that adds huge value to our lives so if she thinks they are all feckless drifters perhaps she should switch of all TV and Radio, all online arts contents, ditch all books, records, CDs, Videos. Almost all successful artists spent years finding the opportunities to use their talents, and need luck as well.
But ditto the Scientists I know, especially since the Brexit vote finding an entry level job in science has been almost impossible, and the journalists, and a lot of successful business people. The arts are not alone in you needing to spend years working your way up, finding the opportunities, learning your craft so do you say that all the aspiring Nobel prize winners, Pulitzer Prize winners and Sir Alan Sugars* should forget their ambitions?
And in all these industries people do casual jobs in the meantime to make ends meet.
As a businesswoman I know that being successful in your job is a product of talent, you are motivated to do what you are good at, and getting the necessary skills and experience, and success, follow. So no offence to Fatima but I am sure she will be better dancing and no doubt in due course teaching dance, than trying to use non existent talent to move into cyber - whatever that is.
