The rise of technocratic institutions is necessary for the well-functioning of a democracy (some are of governance require an expertise that is not expected from common citizens). This is why in history many more independent institutions were created (Bureaucracy, banks, courts, trade treaties). Also, an advantage was that those institution are taken away from the control of the govern,went that looks for immediate re-election, and therefore are suppose to implement more measures looking at the long term rather than at the short-term.
