Less so these days. Most retired classical musicians (ones who retired after a long career) I know grew up fairly well off but now scape a living off of lessons. Admittedly the ones I know skew Vocalist, and they've always been poorer.

But the ones who had their debut during the golden days of Opera in the 50s-early 60s do have some of that. Parties at people's estates with footmen serving up drugs on platters.
