NBER are a bunch of lampshades who inhale air conditioners through their anuses
There haven't been the two consecutive quarters of decreased GDP (the traditional definition of recession), but we might find out that the 4th quarter will fulfill that. NBER can't risk that, though. They need a recession under a Republican president, so that an incoming Democrat can take credit for "fixing the economy." So they're just changing the rules to fit their agenda.
