Of course most people cannot understand the difference of the sound between the best violin player holding the best violin and an average player with a budget organ.
This is exactly what I was thinking as well and what provokes me to say if you at for street performers for lessons you just don't know what you are going to get
Do you think that if it was a warm June evening lets say around 18-20:00 and in a park with grass the results would be the same? There are many more factors to mention that we can end up with a musician being surrounded by hundreds of people and much more money.
Location and time is always important factors when performing in public. It is even more important than the performer themselves if they measure performance success in terms of the $. I think this experiment highlighted that perfectly (amongst other windows into how the general public behave).
For the payment subject. Do you pay taxes for all the money you receive? In my country teachers NEVER give a payment proof, so they don't pay taxes. These taxes now are shared among all the other civilians that cannot cheat from the tax office.
In the "Western world" you are expected to pay taxes, I guess there are some countries such as your own where teachers are not required to pay taxes. If you earn under a certain amount per year most western economies will not require you to pay any tax at all, I am sure you do not know the exact details of the monies that all the teachers in your country make most might only teach as a past time and earn very little per year thus do not require to declare any tax.
The writer has two kids as she mentions. Do you have an idea what her financial situation is? Why pay for a good 60$ teacher while she can hire a cheaper one and if her kid goes well she will "break out my wallet for the big guns.". In fact i know examples of children that started and gave up after even less than a year.
I agree do not pay big bucks for an excellent teacher to begin with. First see if your child likes the piano, get them to learn from any cheapo teacher. However the pitfall of hiring a cheap teacher is that you get a cheap service and you really get what you pay for. I charge more than most teachers and my students realize why after the first few lessons. Students of mine who had no teacher before have no idea how good the lessons really are, but those who come from other teachers highlight how much faster they progress and how much more interesting I make it. I am happy to blow my own trumpet here because I am very proud of my teaching craft and have been blessed with meeting the right people have having the right experiences to guide me on this path. Thus I happily increase my teaching fees because I know my product is better than the teachers who teach cheap and from a book or a set course, who have no idea of how music flows through the individual and the individual musical paths that are out there, has no concept of efficiency of learning and treat students like cattle.
Cheap teachers are also generally inexperienced teachers. They are cheap because they can get more customers that way, it keeps them competitive and people with little musical education knowledge will of generally choose the cheaper option. If I where cheaper I would get such an excess amount of students I would not have enough time in the week to deal with it. These cheap teachers charge a lesser fee and still have room to fit in more, says a great deal about their musical networking.
You are looking from the one side, yours, and you see what you want to see. You can't even understand the humor. Relax, read again, think again.
Think about what again? And I am relaxed, I don't see where I have been the opposite (*maybe my use of ! but it is more of an amazed emotion rather than anger). Even if it is humor it can be considered in more constructive terms as well, that was my choice and has nothing to do with being angry or unrelaxed.
