But here’s the thing. Mnuchin’s shameless posturing about the administration’s tax plans—at one point he even promised there would be “no absolute tax cut for the upper class,” which was a laugher given every proposal Trump had ever backed—points to a deeper problem. The man regularly says things that just aren’t true. He’s been claiming that there was an analysis underway. There wasn’t. And while a lot of people may roll their eyes about that in the context of a wonky tax debate, his complete lack of credibility is going to be a problem if we ever run into a serious economic or financial crisis. Just ask yourself: If the markets were crashing and Steve Mnuchin held a press conference assuring everybody that the administration had an action plan in the works, would you believe him? His complete detachment from reality has mostly been an infuriating sideshow during this tax push. If stuff ever really hits the fan, though, his reputation for fibbing is going to make things even worse. Just like someone else we know.
