To see why, one need only understand how the government calculates personal savings. Not surprisingly, the calculation is a simplistic one that involves a subtraction of cash outlays from disposable income. David Malpass, NRO Financial writer and chief economist at Bear Stearns, recently noted that savings statistics understate actual additions to savings by excluding cash flow improvements from realized gains on equities, houses, and mortgage refinancings. Importantly, the government savings rate either cannot factor in, or would calculate negatively, how Americans purchase the instruments of the wealth that Malpass mentions.
To begin with, 401(k) accounts have become highly popular investment vehicles for Americans over the last 20 years. Since 401(k) deposits come out of pre-tax income, the significant savings built up within those accounts would not factor into government calculations of money saved over outlays.
