I did mean to say ему, my mistake. And I guess it would be more appropriate to say "капатализм Америки ему не очень нравится," but in this poem he is attacking family life, racism in America, "artists" in America, and business.
He did not attack family life or artists in America at all. He just chose the worst possible versions of these entries to show that it is what (by his opinion) the capitalism is and what the capitalism leads to.
