Here’s a thought experiment. Suppose the year is 1902. Automobiles exist, but they are rare and expensive. The assembly line has not yet been invented, and car manufacturing, such as it is, is done entirely by craft methods.
Now imagine that our politicians decide that every American family, as a matter of national policy, should have its own automobile. (Let’s also stipulate that the trades involved in automobile-building–machining, welding, carpentry, etc–are tightly controlled by guilds.)
What would happen?
