@jespah,
jespah-
If the reason why public servants get good pensions, etc. is to attract and retain better talent, then I think that the hiring process and the day-to-day retention and firing process would reflect it.
However, at least with respect to the civil service portion of public servants, I think hiring is done from lists that result from scores on tests that are not known for selecting the best and the brightest. Once hired, they are usually retained, even for those found to perform poorly.
