Lets put some information out there about CALPers. You make it sound as if everyone starts there and stays 5 years and retires. The average CalPERS retiree worked for 19.93 years. By dividing the average annual pension for a CalPERS participant in 2012, $30,456, by the average years of service, 19.93. The result, $1,528, is the amount the average CalPERS retiree accrued in annual pension benefits for each year they worked during their careers. I am not saying that this isnt generous by today's horrible standard of retirement planning for the middle class, but neither is it "better than Greece" with people abusing the system.
As for government run entities, "there have been many empirical studies examining the efficiency of government bureaucracies versus business in a variety of areas, including refuse collection, electrical utilities, public transportation, water supply systems, and hospital administration. The findings have been mixed. Some studies of electric utilities have found that publicly owned ones were more efficient and charged lower prices than privately owned utilities. Several other studies found the opposite, and yet others found no significant differences. Studies of other services produced similar kinds of mixed results. Charles Goodsell is a professor of Public Administration and Public Affairs at Virginia Polytechnic Institute and State University who has spent much of his life studying bureaucracy. After examining these efficiency studies, he concluded: “In short, there is much evidence that is ambivalent. The assumption that business always does better than government is not upheld. When you add up all these study results, the basis for the mantra that business is always better evaporates.”
