Kevin Williamson writes Welcome to the Paradise of the Real in The National Review Online. It is a bit long but quite worthy of the time to read it in its entirety.
With economic models, we are a little like Neo in The Matrix, before he takes the red pill: We are not in the real world, but in a simulacrum of it, one that has rules, but rules that can be manipulated by those who understand the code. Economic models and analysis are very useful, but it’s worth taking the occasional red-pill tour, leaving behind the world of pure symbolism and taking a look at the physical economy.
Welcome to the paradise of the real.
The physical economy — the world of actual goods and services — looks radically different from the symbolic economy. Measured by practically any physical metric, from the quality of the food we eat to the health care we receive to the cars we drive and the houses we live in, Americans are not only wildly rich, but radically richer than we were 30 years ago, to say nothing of 50 or 75 years ago. And so is much of the rest of the world. That such progress is largely invisible to us is part of the genius of capitalism — and it is intricately bound up with why, under the system based on selfishness, avarice, and greed, we do such a remarkably good job taking care of one another, while systems based on sharing and common property turn into miserable, hungry prison camps.
Measurements of wealth are limited. Not everything that is worth measuring can be measured. Just because we have measurements does not mean those measurements accurately describe reality.
