I've seen this happen at a lot of large bureaucracies, including my own company - problem arises, and CEO feels compelled to appoint a special "czar" to deal with the problem. This only creates additional problems:
- Being appointed directly by the executive, the czar is not responsible to anyone
- The special czar will be appointed without any additional budget, and thus has no power
- Being outside of the conventional hierarchy, no one reports to him, and thus will find difficulty obtaining cooperation from other groups
- Responsibility for the problem will already be clearly defined in the existing hierarchy - appointing a czar will only confuse existing responsibilities and create conflict with the group responsible for the problem.
I foresee the same problems arising here if an "Ebola czar" is created.
