5. Just why the Roman government, once so powerful and so universally respected, finally became unable longer to defend its borders and gave way before the scattered attacks of the German peoples, who never combined in any general alliance against it, is a very difficult question to answer satisfactorily. The inhabitants of the Empire appear gradually to have lost their energy and self-reliance and to have become less and less prosperous. This may be explained partially at least by the following considerations: (1) the terrible system of taxation, which discouraged and not infrequently ruined the members of the wealthier classes; (2) the existence of slavery, which served to discredit honest labor and demoralized the free workingmen; (3) the steady decrease of population; (4) the infiltration of barbarians, who prepared the way for the conquest of the western portion of the Empire by their fellow-barbarians.

Oppressive taxation.

It required a great deal of money to support the luxurious court of the emperors and their innumerable officials and servants, and to supply "bread and circuses" for the populace of the towns. All sorts of taxes and exactions were consequently devised by ingenious officials to make up the necessary revenue. The crushing burden of the great land tax, the emperor's chief source of income, was greatly increased by the pernicious way in which it was collected. The government made a group of the richer citizens in each of the towns permanently responsible for the whole amount due from all the landowners within their district. It was their business to collect the taxes and make up any deficiency, it mattered not from what cause. This responsibility and the weight of the taxes themselves ruined so many landowners that the government was forced to decree that no one should desert his estates in order to escape the exactions. Only the very rich could stand the drain on their resources. The middle class sank into poverty and despair, and in this way the Empire lost just that prosperous class of citizens who should have been the leaders in business enterprises.

Slavery.

The sad plight of the poorer laboring classes was largely due to the terrible institution of slavery which prevailed everywhere in ancient times. So soon as the Romans had begun to conquer distant provinces the number of slaves greatly increased. For six or seven centuries before the barbarian invasions every kind of labor fell largely into their hands in both country and town. There were millions of them. A single rich landholder might own hundreds and even thousands, and it was a poor man that did not have several at least.

The villa.

Land was the only highly esteemed form of wealth in the Roman Empire, in spite of the heavy taxes imposed upon it. Without large holdings of land no one could hope to enjoy a high social position or an honorable office under the government. Consequently the land came gradually into the hands of the rich and ambitious, and the small landed proprietor disappeared. Great estates called villas covered Italy, Gaul, and Britain. These were cultivated and managed by armies of slaves, who not only tilled the land, but supplied their master, his household, and themselves with all that was needed on the plantation. The artisans among them made the tools, garments, and other manufactured articles necessary for the whole community, or "family," as it was called. Slaves cooked the food, waited on the proprietor, wrote his letters, and read to him. To a head slave the whole management of the villa was intrusted. A villa might be as extensive as a large village, but all its members were under the absolute control of the proprietor of the estate. A well-organized villa could supply itself with everything that it needed, and found little or no reason for buying from any outsider.

Slavery brings labor into disrepute.

Quite naturally, freemen came to scorn all manual labor and even trade, for these occupations were associated in their minds with the despised slave. Seneca, the philosopher, angrily rejects the suggestion that the practical arts were invented by a philosopher; they were, he declares, "thought out by the meanest bondman."
