I get it, there are too many artists out there. Museums can’t possibly show them all, or even a majority of them. But why do so few galleries get to control what becomes famous in the future or not. This question really hurts the art industry as a whole. When academics look back at major art museum exhibits, they are not going to see a proper representation of what is produced today. In fact, they won’t even see a proper representation of quality. All historians will see is what was decided to be commercially successful.
If we don’t want a lack of diversity in the US art world, then museums need to shut the galleries out and do more of their own homework.
