Only if they are. Some pensions are well managed. Some are not. Some seem well managed for years, but in fact they are not. Some have been well managed for a long time, but someone incompetent gets in power. Can you tell the difference.
Oh, and if you can tell the difference, can you convince everyone else and thus get this fixed? Or will voters be happy with the mismanagement because it is returning great results now on low investment leaving more money to spend on other things now?
