Should George Saunders continue writing stories similar to his ground-breaking early work?

 I'm feeling like a hypocritical reader (Lecteur, Hipocrite!) but I'm having a lot of trouble w/ George Saunders's story, Ghoul, in current New Yorker, trouble in the sense that it's a long story and I can't even bring myself to finish reading it in that it all seems such familiar ground and could be/could have been Saunders story ca 1990 when he was just breaking through and his works seemed - were! - strikingly original and weird and in their sly way - most were stories about people in some not too distant future in a somewhat Earthlike planet - employed as  human props in various diorama and amusement parks and in the end each story felt strangely allegorical, in that: What if we all are props in some vast otherworldly game? And in fact, aren't we? Plus many stories about misfits and eccentric losers told with a great deal of empathy and insight. OK, I have been a Sanders champion from the outset, though I registered my disappointment in his (only) novel, Lincoln at the Bardo, which felt like it was forced out into novel length because it is and always has been really hard for a writers of stories only to get the major literary props (Munro aside). And then Lincoln/Bardo gets a Booker Prize, first awarded to a U.S. writer I think, so who am I to judge. He was trying something different, for him, and it obviously worked. So here I go criticizing him when he returns to the ground of his earlier success; the guy can't win! But Ghoul just feels so much like material revisited and already bled dry. So I take it back, George Saunders! Try different forms and milieux, you probably have a lot to say. In fact, I did very much like the previous NYer GS story, a letter, sent sometime in the near future, from a grandfather to his young grandson, about an America stepping ever closer to fascism and about his guilt and shame for not doing more to resist - for GS, a straightforward and emotional piece, quite different from much of his other work.
