Your favorite painting was likely commissioned by a rich person, and the person who received credit for it probably had most of the work done by an apprentice of theirs.
Rich people don’t like fine art and wine because they are so much more intellectually advanced than we are, they like them because they are a great tool of the wealthy. These people can’t tell the difference between a $7 wine and their $25,000 wine in a blind taste test, and if you tell them so, they will smile and nod, because the taste isn’t the point.
Your grandmother’s knit sweaters would be considered fine art if it could be used to launder money.
