We'll see how much of the thread is about the skilled trades and how much of it is about the Koch Brothers role in horse-race US politics, and then we'll revisit.
I don't think that the direction of the discussion necessarily imbues the value of an HN post. I also don't think that the skilled trades themselves were the focus of the post; rather, the focus was on what the Koch Brothers did for his foundation, and how it contrasts with their reputation.
