Our lords and masters (h/t Americablog):
Those trends came as real income dropped 0.5 percent for the month.
The Labor Department said its Consumer Price Index increased 0.5 percent after rising by the same margin in February. That was in line with economists expectations.
Core CPI is vindication for officials at the Federal Reserve who have viewed the recent energy price spike as having a temporary effect on inflation.
Food and gasoline rose 0.8 percent, the largest gain since July 2008, after increasing 0.6 percent in February.
When thinking about inflation, think of individual’s (or companies) surplus income, that is, how much income do they have left to spend after their necessities. Necessities include food, housing, heating and transportation. To a lesser extent, clothes, though most people don’t need to buy clothes every month.
Goods inflation, that is to say, core inflation, is mostly in items that you don’t have to buy. Sure, you might want to, but you don’t have to have a new toaster, or TV, or computer. Food, on the other hand, you have to have. If you live off rapid transit, and most Americans do, then fuel for your car is something you have to have otherwise you can’t get to your job: you must buy it, at whatever price it is selling for. Heating oil is something you have to have, freezing to death is bad.
If you earn $2k a month and your fixed bills come to $1,600, your expendable income each month is $400. If oil and food rise enough that you have to spend an extra $50 you’ve lost 12.5% of your income. If they rise enough to cost you $100 a month, 25%. That margin is what matters to most people. And for people close to the line, the extra money they must spend may kick them from surplus into a personal deficit, at which point they have to start borrowing money, usually at usurious credit card rates of over 20%.
The day laboring class is particularly vulnerable to this. A bit of drying up of work, an increase in the price of food, and they can reach the point where they can’t afford to eat enough every day. When that happens you either get a revolution, or you get famines. This was particularly a factor, by the way, in Egypt.
Inflation in what people must have is what matters to most of the population. But it isn’t what matters to your lords and masters. Food costs and fuel costs, are, for them, roundoff errors. If you’re really rich, spending $1,000/day on food doesn’t even show on the scale. So, by and large, goods inflation is what matters to them, personally, though they may have business concerns about fuel inflation (and note that inflation in oil leads to food inflation very directly. Modern agriculture is how we turn oil into food, essentially.)
So when someone talks about core inflation being the most important form of inflation, check your wallet, it’s likely lighter than it used to be.
