Quick takeaway: Man did the Obama people fuck up, and some of those Obama people (cough Jason Furman cough) are doing their best to get Biden to fuck this one up too.
Trump bucks and Biden bucks worked their magic, and "showering people with money" should be understood as the obvious and easy fix to any severe economic downturn but we just got lucky this time. The Furmans will be quicker on the draw next time to kill anything good.
