It's true, and that's exactly why it's a catastrophic idea and should be property identified as a form of corruption. In those countries (and you have some form of those issues creeping in western countries if you look attentively) you have an elite, a cast forming around some aspect of public management as the only way to get those kind of job is to get enough money to get it and the only way to get enough money is to be part of the cast. As such after only one generation those positions are filled by people that are 1) not the best and 2) often incompetent.
