In a column explaining why he’s terrified that the “Modern Monetary Theory” folks might get anywhere near the levers of power, Tim Worstall fits in the best reason to cut taxes:
Given that we are discussing monetary policy it seems appropriate to bring Milton Friedman in here. And he pointed out that if you ever have a chance to cut taxes just do so. On the basis that politicians, any group of politicians, will spend the bottom out of the Treasury and more however much there is. So, the only way to stop ever increasing amounts of the the entire economy flowing through government is simply to constrain the resources they can get their sticky little mits on. We could, for example, possibly imagine a Republican from the Neanderthal wing of the party arguing that what the US really needs is another 7 carrier battle groups. And one from the even more confused than usual Progressive end of the Democratic Party arguing that each college student needs her own personal carrier battle group to protect her from the microaggressions of being asked out for a coffee. You know. Sometime. Maybe. If you want to?
