Steven Malanga in the LA Times how public service unions have financially raped Californians.

When California’s government employee pension system was established in 1932, it was a model of restraint. Private-sector pensions were still rare then, but California lawmakers had a particular reason for wanting a public-sector pension system: Without one, unproductive older workers had an incentive to stay on the job and just “go through the motions” to get a paycheck, as a 1929 state commission put it. Pensions would encourage those workers to retire. The commission cautioned, however, against setting a retirement age so low that it would “encourage or permit the granting of any retirement allowance to an able-bodied person in middle life.”

Accordingly, California set its initial retirement age for state workers (and, beginning in 1939, for local government employees) at 65, at a time when the average 20-year-old entering the workforce could expect to live for another 46 years, until age 66. The system’s first pensions were modest, though far from miserly. An employee’s pension equaled 1.43% of his average salary over his last five years on the job, multiplied by the total number of years he had worked. That formula typically provided longtime workers with pensions equal to half or more of their final salaries.

The pensions were funded by three sources: contributions from employers (that is, state and local governments); contributions from employees (though some governments opted to cover that expense); and money that the pension fund would gain by investing those contributions. With the 1929 stock market crash in mind, California opted for a cautious investment approach.

“An unsound system,” the 1929 commission warned, would be “worse than none.” The employees’ contributions were fixed, so if investment returns weren’t sufficient to fund the promised pensions, the employers’ contributions would have to increase to make up the difference.

In the decades since, that cautious approach has been virtually abandoned as public employee unions have taken control of the system. The retirement age has been lowered, benefits have been increased and investments have become far riskier.

The major changes began in the late ’60s, during a time of rapidly growing public-sector union power. In 1968, the Legislature added one of the most expensive of all retirement perks — annual cost-of-living adjustments — to CalPERS pensions. Other enhancements followed, including, in 1970, a far more generous pension formula that would allow an employee who worked for 40 years to retire at 60 and collect an annual pension equal to 80% of his salary. If he kept working for another five years, his pension fattened to 90%. In 1983, public safety workers got an even better pension formula, and the age at which they could start collecting was dropped to 55.

Not surprisingly, the costs of the enlarged pensions weighed heavily on California’s budget. In 1991, with the nation mired in a recession and the state in a fiscal crisis, the Legislature closed the existing pension system to new workers, for whom it created a second tier. This less-expensive plan no longer required workers to make pension contributions, and it lowered the value of the pension to 1.25% of final average salary for every year worked; further, a worker couldn’t begin to receive the pension until age 65.

But that economy lasted only until 1999, when the fund’s board concocted an astonishing proposal that would take all the post-1991 state employees and retroactively put them in the older, more expensive pension system. The initiative went further, lowering the retirement age for all state workers and sweetening the pension formula for police and firefighters even more.

CalPERS wrote the legislation for these changes and then persuaded lawmakers to pass it. In pushing for the change, though, the pension fund downplayed the risks involved. A brochure about the proposal that CalPERS handed to legislators read like a pitch letter, not a serious fiscal analysis. It didn’t mention that state law protected government pensions, so that taxpayers would be on the hook for any shortfall in pension funding. In essence, the CalPERS position was that government workers should carry zero risk, sharing the bounty when the fund’s investments did well but losing nothing if investments went south…
