There has been an awful lot of discussion in recent months about whether government debt is a burden for future generations. The discussion has gone something like this: those who believe government debt is a burden claim that it is a burden because future generations have to repay taxes for present spending, those who believe that it is not claim that every debt is also credit, and so because the next generation will inherit not only the debt but also the credit, that government debt is not in itself a burden to future generations, unless it is largely owed to foreign creditors.
It is relatively easy to calculate what the monetary burden of government debt is. Credit inheritance and debt inheritance are not distributed uniformly. The credit inheritance is assumed strictly by bondholders, and the debt inheritance is assumed strictly by taxpayers. Each individual has a different burden, equalling their tax outlays, minus their income from government spending (the net tax position).
For an entire nation, everyone’s individual position is summed together. In a closed economy where the only lenders are domestic, the intergenerational monetary burden is zero. But that is by no means the entire story.
First, debts to foreign lenders are a real monetary burden, because the interest payments constitute a real transfer of money out of the nation. Second, while there may be little or no debt burden for the nation as a whole, interest constitutes a transfer of wealth between citizens of the nation, specifically as a transfer payment from future taxpayers to creditors. This adds up, at current levels, to nearly half a trillion of transfer payments per year from taxpayers to creditors. So while the intergenerational burden may technically add up to zero for the nation, it will not for individuals. The real burden is huge transfers from those who pay the tax to those who receive the spending, and those who receive the interest. So who loses out?
Here are the figures for 2009 showing net tax position for each income quintile:
Bottom quintile: -301 percent
Second quintile: -42 percent
Middle quintile: -5 percent
Fourth quintile: 10 percent
Highest quintile: 22 percent
Top one percent: 28 percent
The negative 301 percent means that a typical family in the bottom quintile receives about $3 in transfer payments for every dollar earned.
What this data does not show are the reverse transfers via interest payments. There is no data (that I can find) on treasury interest payments received by income quintile, but assuming that the top quintile dominates income from interest (as they dominate ownership of financial assets, owning over 95% of all financial assets) this leaves the lower income quintiles benefiting from transfer payments, the top quintile benefiting from interest (as well as policies like bank bailouts, corporate subsidies, and quantitative easing, whose benefits overwhelmingly benefit the top quintile), and squeezing the taxpaying middle quintiles who receive neither the benefits of interest payments, nor significant welfare transfers.
To misquote George Orwell, when it comes to the national debt and who takes its burden, some pigs are definitely more equal than others.
