Justifying Hans Haacke as Art

Question !: On page 161, I liked the phrase "cultural process of meaning production." The use of the word "cultural" seems to imply that more than one person gets to create the meaning. However, people of a common culture are lumped together in that culture. So instead of the art piece having a meaning for each viewer, it has a "cultural[ly]" determined...predetermined... (fixed?) meaning. I thought the author was saying that the artists explore how ant art piece can have different meanings in different circumstances, but he seems to have condensed it down to different cultures instead. Is my understanding correct? What doe this phrase really imply?

Question @: In the last paragraph, the author concludes by saying that Haacke's work makes you aware that "economic and social conflicts are not, in reality, "alien" to the museum's harmonious space" (last page). This made me think of Andrea Fraser's Museum highlights and how she was pointing out the "economic and social conflicts" behind the museum. I wonder if whichever came first in the timeline influenced the other, and what other artists critiqued the capitalism of the museum? Also, If Haacke's work had been allowed, would it have raised an uproar? Is it only significant because it wasn't liked at first? Would it have said anything about the museum's impurity when it comes to the classes?
