Hi Bob....yes we'll see the rich but they don't always have good practice habits.
I had one adult student who lost his job and had to quit. 25% of my students dropped out this last spring. (I had 40) Not all of the reasons were clearly financial, but I think it is a domino effect.
How, pray tell, will any amount of practice make for a good musician, if that potential musician cannot afford lessons, and therefore has nothing to practice? Have you any idea what anguish that engenders in the motivated individual?
