If people listened to Coolidge more reconciliation may not be a question nor New Deals and all that.
Post New Deal, the Slash and Burn would be just fine, but sadly even Reagan had no friends in the GOP congress. Libertarians of past generations spent a lot of time hero worshiping one guy and acting as a debate society, so now our policies adapt to current practicalities. Which is why your not seeing “Ban welfare now,” and Zero Percent tax rates. Baby steps are forced on the biggest anarchist due to the past generational mistakes.
