This seems to be his approach when he has something he wants to do, he creates an new level of government bureaucracy to insulate himself from the failure.
Well since unemployment is his top priority now, He needs to create some sort of bureaucracy that he can then give jobs to his cronies. That way he can say he created more jobs, on top of the millions he says he created. Besides Tom Dasle is still unemployed and what better way to get him a job if he is not vetted, just appointed.
A Job Czar? Good question. I'd imagine Barry would want to consult with his Czar Czar about it and if it looks like one is needed then the Czar Czar will notify the teleprompter.
