From the article: “The suspensions have often come at the request of affected industries.”
Given the evident failure of “Supply-Side” (aka “Trickledown”) economics, it’s worth noting that, as far as I know up to this point, Trump and the GOP have not specifically identified that theory as a reason for their ease up on industries. And the Dem side of Congress have not yet capitalized on that by bringing up its obvious avoidance by the other side; I believe that any Dem plan for 2018 should include that, focusing on and bringing up over and over again how supply-side in actual practice ended up hurting us AND how it only served to benefit those (easily filled in blank) who needed much, much more of what they already had much, much more of: https://www.americanprogress.org/issues/economy/news/2012/08/01/11998/the-failure-of-supply-side-economics/
