As usual, John is on target.
Noah Smith has an interesting Bloomberg View piece on Japanese inflation. Three crucial paragraph struck me
... Japanese unemployment is very low, and the economy is expanding at or above its long-term potential growth rate of around 0.5 percent to 1 percent. So according to mainstream theory, inflation would be an unnecessary and pointless negative for Japan’s economy. Why, then, are there always voices calling for Japan to raise its inflation rate?
Actually, there are several reasons. The main one is that inflation reduces the burden of debt. Japan’s enormous government debt represents the government’s promise to transfer resources from young people (who work and pay taxes) to old people (who own government bonds). Since Japan is an aging society, there are more old people than young people. That makes the burden especially difficult to bear. Young people also tend to have mortgages, the repayment of which is another burden.
Sustained higher inflation would represent a net transfer of resources from the old to the young. That would increase optimism, and hopefully raise the fertility rate, helping with demographic stabilization. It would also decrease the risk that the Japanese government will eventually have to take extreme measures to stabilize the debt.
I like these paragraphs because they so neatly distill the language used by the standard policy establishment to advocate inflation. Noah clearly separates the usual "stimulus" arguments from the new "debt" argument, which helps greatly.
Debt is a "burden." Sort of like snow on your roof, debt appears from the sky somehow and then represents a "burden" requiring "lifting," which would be beneficial to all.
Debt "represents the government’s promise to transfer resources from young people ... to old people.." Apparently, the government woke up one morning, and said "we promise to grab about two and a half years worth of income from young people and give it to old people." Undoing such an ill-advised promise does indeed sound worthy.
But, lest these soothing words lull you into idiocy, let us remember where debt actually comes from. The Japanese government borrowed a lot of money from people who are now old, when they were young. Those people consumed less -- they lived in small houses, made do with fewer and smaller cars, ate simply, lived frugally -- to give the government this money. The promise they received was that their money would be returned, with interest, to fund their retirements, and to fund their estates which young people will inherit.
Noah is advocating nothing more or less than a massive government default on this promise, engineered by inflation. The words "default," "theft," "seizure of life savings," apply as well as the anodyne "transfer." I guess Stalin just "transferred resources."
