Does that ever happen in the private sector?
What you guys always fail to consider is that when you look at government employees they only have one CEO. In the private sector there are nearly 7 million CEOs ~ not that all of them are getting rich of course, but they are part of the "work force".
The government employees didn't invent the double-dip gimmicks, or how to boost your tap on the company pension fund at the end of your career with lots and lots of fake overtime. That came out of private sector dealing with IRS and with the federal and state agencies that regulate pension rights ~ and who look for criminals attempting to bilk pension plans.
If you need some supplemental education concerning how pension plans get bilked take a look at the history of LTV ~ and its pension plans.
As a taxpayer you are paying for their management ~ and to some degree their payments! The company started out by attempting to clawback what they called "excess contributions" ~ which used to be a much more common practice today. That's pretty much like management claiming 'management overtime' ~ and the pattern follows the public employee union deals where end of employment overtime counts double ~
Look here, the term "bilk" is derived from a Romany word "bilco" which means, little thief ~ with the implication being "A minor tapping that pays off for many years". Golden parachutes are in the same class, as is the Pigeon Drop Game.
So, how do you keep traditional Gypsy scams out of government retirement systems? Well, you do it the same way you keep them out of private sector management retirement systems, or private sector union managed retirement systems, or out of stores where someone drops what seems to be a large wad of money which they agree to share with you after they check with the store manager ~ provided you put up some earnest money.
