Crashing faster, a bit later

NEW YORK (Reuters) - New Jersey’s treasurer said on Thursday she will increase the expected rate of return for the state’s struggling public pension system from 7 percent to 7.5 percent, then lower it again over time.
The switch to a higher assumed rate means that the state, and participating local governments in New Jersey, will for now escape the higher costs that arise when investment return assumptions are lowered.

Thus year, lucky pensions can hope for a 5% return.  Raising above this number is tax payer catastrophe at this point.
