Why Nations Fail: The Origins of Power, Prosperity, and Poverty

technological development—an all-too-common occurrence due to the fear of creative destruction. The great Roman writer Pliny the Elder relates the following story. During the reign of the emperor Tiberius, a man invented unbreakable glass and went to the emperor anticipating that he would get a great reward. He demonstrated his invention, and Tiberius asked him if he had told anyone else about it. When the man replied no, Tiberius had the man dragged away and killed, “lest gold be reduced to the value of mud.” There are two interesting things about this story. First, the man went to Tiberius in the first place for a reward, rather than setting himself up in business and making a profit by selling the glass. This shows the role of the Roman government in controlling technology. Second, Tiberius was happy to destroy the innovation because of the adverse economic effects it would have had. This is the fear of the economic effects of creative destruction.
    There is also direct evidence from the period of the Empire of the fear of the political consequences of creative destruction. Suetonius tells how the emperor Vespasian, who ruled between AD 69 and 79, was approached by a man who had invented a device for transporting columns to the Capitol, the citadel of Rome, at a relatively small cost. Columns were large, heavy, and very difficult to transport. Moving them to Rome from the mines where they were made involved the labor of thousands of people, at great expense to the government. Vespasian did not kill the man, but he also refused to use the innovation, declaring, “How will it be possible for me to feed the populace?” Again an inventor came to the government. Perhaps this was more natural than with the unbreakable glass, as the Roman government was most heavily involved with column mining and transportation. Again the innovation was turned down because of the threat of creative destruction, not so much because of its economic impact, but because of fear of political creative destruction. Vespasian wasconcerned that unless he kept the people happy and under control it would be politically destabilizing. The Roman plebeians had to be kept busy and pliant, so it was good to have jobs to give them, such as moving columns about. This complemented the bread and circuses, which were also dispensed for free to keep the population content. It is perhaps telling that both of these examples came soon after the collapse of the Republic. The Roman emperors had far more power to block change than the Roman rulers during the Republic.
    Another important reason for the lack of technological innovation was the prevalence of slavery. As the territories Romans controlled expanded, vast numbers were enslaved, often being brought back to Italy to work on large estates. Many citizens in Rome did not need to work: they lived off the handouts from the government. Where was innovation to come from? We have argued that innovation comes from new people with new ideas, developing new solutions to old problems. In Rome the people doing the producing were slaves and, later, semi-servile

with few incentives to innovate, since it was their masters, not they, who stood to benefit from any innovation. As we will see many times in this book, economies based on the repression of labor and systems such as slavery and serfdom are notoriously noninnovative. This is true from the ancient world to the modern era. In the United States, for example, the northern states took part in the Industrial Revolution, not the South. Of course slavery and serfdom created huge wealth for those who owned the slaves and controlled the serfs, but it did not create technological innovation or prosperity for society.
N O O NE W RITES FROM V INDOLANDA
    By AD 43 the Roman emperor Claudius had conquered England, but not Scotland. A last, futile attempt was made by the Roman governor Agricola, who gave up and, in AD 85, built a series of forts to protect England’s northern border. One of the biggest of these was at Vindolanda, thirty-five miles west of Newcastle and depicted on Map 11 at the far northwest of the Roman Empire. Later, Vindolanda was incorporated into the eighty-five-mile defensive wall thatthe emperor Hadrian constructed, but in AD 103, when a Roman centurion, Candidus, was stationed there, it was an isolated fort. Candidus was engaged with his friend Octavius in supplying the Roman garrison and received a reply from Octavius to a letter he had
