Many readers have asked me to explain why social security and pension schemes run by national governments can never become insolvent. Some have heard me commenting on the radio recently about this. In the current recession, where automatic stabilisers are pushing the budget back into deficit to dampen the fall in aggregate demand there are now renewed cries that social security funds around the World are likely to become insolvent. There are the familiar howls that all the “debt” that is being built up as governments go into deficits (mostly because they have been dragged into them by the cycle) will require huge future tax burdens that will undermine the capacity of governments to deliver adequate social security and health care systems. I think its time to de-brief again. The short answer to these claims is: sovereign governments can always fund social security in their own currency. Always, always, and even always.
