The government recently announced that the national debt reached $30 trillion. It now stands at 128% of the economy. Yes, our national debt is larger than what we earn each year. Wow. You would think that they would be so ashamed that they would somehow hide that obscene accomplishment. I guess its hard to hide such things. That debt amounts to about $90,000 for each person and $240,000 per tax payer.
Equally troubling is that the $30 trillion announcement had almost no effect. If Biden burps at the dinner table the stock market falls. If the inflation rate rises by a tenth of a point, interest rates skyrocket. But debt reaches $30 trillion. Ho hum, honey pass the mustard please.
I read several articles announcing this new debt number and came away from that experience with a tummy ache. Lots of angles here and its not really an all-good or all-evil story.
Take for example, the idea that the debt is $240,000 per tax payer. My first reaction is wow -- huge. But that reaction stems from the illogic of comparing a stock with a flow. The debt is a stock, an accumulation of what we owe. The flow is what we earn each year. We have a lot of years, if we so chose, to earn income and pay off the debt.
We do that as households every day. We borrow a ton of money for our nice new house or our sleek cool Jaguar and then we spend 30 years paying it off. We might only make $50k per year but in 30 years we can pay off a pretty big chunk of debt. If our national debt is $240,000 per taxpayer, note that we have a lot of years to pay.
Maybe that's good or not good. Take the case of the house purchase. Hoot might buy a really cool house and doesn't mind paying a big chunk of his income every year. Kiltie might buy a less worthy house and feel like he got scammed. It's the same with the national debt. What are we doing with all that debt? Are we throwing it down a hole or are we using it to our great advantage?
Hmm. Answering that question is full of politics. It all depends on what you think the government ought to do with our money. Danny wants us to spend it all on national defense and infrastructure. Jason wants us to make incomes more equal. Nolan wants more spending on Kraft macaroni and cheese.
It also depends on the realities of the impacts. If we spend it on national defense and we lose the next war, then it seems like we could have used that money better. If we spend it on welfare and poverty worsens, then we wonder if we are wasting the people's money.
Government always has the choice as to spend the money on donuts or steel. Donuts are a consumption item. You spend the money, you eat the donut, you get a sugar high, and then that's about it. The government could instead buy steel. Steel is an example of a capital good. The essential characteristic of the steel is that it lasts and it can lead to even more output. The extra steel lets you build a building. The building might house a donut machine and produce donuts for years to come. Steel or donuts? Consumption or investment?
Finally, regardless the above points, there must be a limit to what is prudential to borrow. Even if you use the proceeds for good things -- one can still borrow too much. Recall that you have to pay it back. If I buy a $10 million dollar house and I live off my Social Security benefit, that is not going to work.
Surely the above does not cover the whole waterfront. But it does support what I said at the outset. How much national debt we can tolerate is not any easy question. Some debt is good. Other debt is not. Knowing what is the right amount is complicated. But I will stick my neck out and say that we could live in the USA with a national debt less than $30 trillion.
