For average person it's rather difficult to understand what is true art and what is just a marketing. However, only because he is afraid of saying his own opinion when its in contra to public one. What make us to be in silence and not to say "I dont understand it!".
Do you remember the movie "1+1"? This perfect moment in art gallery "USD 35 000 for this?!"
Not sure tt "nothing is sacred anymore". Most likely, dont wanna to believe in it...
