I’m one of them. I work a good tech job and do photography as a hobby.
Forgive me if I seemed overly focused on these folks and their lucky circumstances. If I’m being honest, I’m a bit jealous they get to spend all their time focused on their creative interests when I only get to do it part time.
If money wasn’t a requirement, I’d be out photographing every day instead of writing web code.
All in all, life is good though, so even if I’m a teeny bit jealous, I’m grateful for how good I have it in life. I’m pretty lucky, all things considered!
I'm impressed by those who find the time and energy to be consistent with a craft, on top of the pressures of work and family.
I like a dabble here and there at lots of things, but don't make the time and don't follow through enough. Something to aspire to.
I know a fair few day jobbing musicians and creatives of other stripes though, only one of which with parents of any real means.
One is a manager at a theatre, one does care work, one does WordPress and a bit of JS for small companies.
The most full-time musician I know did have the richest parents growing up, but he makes his cash teaching and doing session stuff in local theatres.
Given how income distributions work, I think day jobbing creatives are very much the majority.
