You're probably in the small minority at least when it comes to forking over material dollars. Most people spending money, at least beyond trade paperback range, are probably looking for something that has at least a plausible connection to real income.

If that was true, no music teacher selling independent lessons would be able to survive.

It's not clear to me that independent tutors are generally getting rich. But there clearly are activities that benefit from individual training. I imagine music is one of those. But that mostly probably falls into the luxury goods category.

"Getting rich" is a substantial movement of the goalposts. The point is that people are spending money outside the trade paperback range on education, either for themselves or for their children (I've seen quite a wide distribution while in the waiting room), that has nothing to do with income.
