Go Back to the OPS?

Under the old pension scheme, the state governments don't really have to set aside money every month into a fund. In the NPS, however, states have to setting aside funds immediately as part of their contribution. So if they make the switch and go back to the OPS, their finances immediately look better. They might even save 7 to 10% of their pension expenditure on pensions. But you and I know that they're simply delaying the inevitable.
