The plan to use the PF to fund government as it stands puts the corpus of the fund at great risk. First I see no inflation proofing in the plan. This year the draw will be three billion plus and without reducing spending the draw will remain the same or more for the foreseeable future.  Now they use a five year average to calculate the PFD so if investment goes down the check will be smaller. If we use a three billion plus draw each year a down market will make it necessary to then draw from the corpus of the fund and a downward spiral of the fund will be the result . The only answer as I see it will be to reduce spending. I hope someone  can prove me wrong.
