Though the plausibility of her claim is suspect — there are only about 350 million Americans, and not all of them work — it actually illustrates a problem that this kind of bill creates.  At some point, the number becomes just a word. It no longer refers to a concept that people can get their minds around. Senator Mitch McConnell, the minority leader, commented this week that if you started on the day Jesus was born and spent 1 million (that’s 1,000,000) dollars each day until now, you still wouldn’t have spent 1 trillion (1,000,000,000,000) dollars. A trillion dollars is huge, but it’s hard to get your mind around how huge. The graph here tries to illustrate. The blue column represents 1 trillion. The column to the left is 1 billion. You can barely see it. The gray columns are the logarithm of the numbers across the bottom. I think people tend to think of big number more like the gray bars indicate. A trillion is bigger than a billion, but it’s not that much bigger.

How big is a trillion?

Will all of that, it’s easier to understand why Speaker Pelosi was having trouble. She’s throwing around all these numbers all the time, but like most people, she only half-way understand them. They’re just words now, so an extra billion here or there is just another digit. My thought is that we ought to be very cautious when those who want to spend our money aren’t careful to understand what they’re spending. But more than that, we ought to make sure that we understand ourselves, so that we don’t have to depend on politicians to explain what they’re doing.
