I said my daughter could paint like a fine artist at Grade 5 level (that's the 5 the year of school). And probably I should have told you that myt entire family is gifted. I suppose it makes a difference. Father's IQ (and brothers) was 185. He spoke 11 languages, had degrees in law, journalism, and engineering. I took that kind of thing for granted,.
Don't put words into my mouth. It doesn't work. I will just correct what I said, and anyone reading this conversation will note what you are doing.
The people who 'earn' the kind of money that is able to pay those kind of prices for art are doing so by paying workers so little that they can hardly survive.
More than that, I'm not sure if you're familiar with the concept of the banality of evil by Hannah Arendtz. She basically said that the guy who created the gas ovens to kill the Jews wasn't a psychopath, and he wasn't evil. He was just a career politicians, and he didn't think deeply about what he was doing at all. She called that the banality of evil. - I was just doing my job.
In the same way, sure actually buying the art doesn't harm poor people directly. However, if you consider how the people got that money, then it becomes something akin to the banality of evil.
After all, if great empires built those empires on slavery, just how ethical were those empires?
