I have young kids. If violin lessons are apparently so expensive as to require you to be a millionaire (not merely, say, a six-figure-earner), what is a class or event I can go to to see all the poor, obese kids that I haven’t come across yet? I don’t live in a frou frou part of my town. It seems more likely to me that cultural forces are at play.
