I recall that only 10% of obamas cabinet had any private sector experience. That was, and continues to be, a damning statistic for them. It shows in the crappy growth under the Obama regime.
Economic growth would have likely been anemic at best under a Republican Presidency during this period, but I seriously doubt a Republican would have doubled down on clearly failing statist policies and increasing regulatory burdens that actually made it worse than it would have been otherwise. They have no ability to envision impact upon the private sector because it’s utterly alien to them, yet they continue to attempt rule by dictat.
