No, but I think it's good when someone with credibility among certain people reiterate something, even if it adds nothing of value to you and me.
Democratic and left-of-center politicians (or "liberal elite economists") can say this until they're blue in the face but Trumpers will dismiss it as I dunno, woke butthurtism or something. But when someone like Buffet says it, at least they (maybe) have to think a little bit before coming up with some mental gymnastics to dismiss him. And maybe along the way they'll question, if only a little bit, the sanity of Trump's policies.
They were thinking of making a Minority Report adaptation (with Arnold, not Cruise) as the sequel to Total Recall, with the mutant Martians as the precogs. Could have been a fun one!
