Then how come the personal saving rate has been in steady decline since 1974 when IRAs were first passed into law? And how come saving didn't improve after 1978 when 401(k) plans were first created? Or after 1997 when Roth IRAs were legislated? The current monthly reading of personal saving is a measly 4.4%.
A rich country saves, a poor one spends.
"Notice that NIPA’s [National Income and Product Accounts] treatment of IRAs and 401(k) plan contributions, for example, is perfectly consistent: Because these defined contributions are not part of personal outlays (and, therefore, must be included in the difference between personal income and personal outlays), they are correctly included in national saving computations."
