If it should be asked what caused the decline of this great civilization, it may be said that the causes were many. In the first place, the laws of labor were despised and capital was consumed without any adequate return. There was consequently nothing left of an economic nature to withstand the rude {265} shocks of pestilence and war. The few home industries, when Rome ceased to obtain support from the plunder of war, were not sufficient to supply the needs of a great nation. The industrial condition of Rome had become deplorable. In all the large cities there were a few wealthy and luxurious families, a small number of foreigners and freedmen who were superintending a large number of slaves, and a large number of free citizens who were too proud to work and yet willing to be fed by the government. The industrial conditions of the rural districts and small cities were no better. There were a few non-residents who cultivated the soil by means of slaves, or by _coloni_, or serfs who were bound to the soil. These classes were recruited from the conquered provinces. Farming had fallen into disrepute. The small farmers, through the introduction of slavery, were crowded from their holdings and were compelled to join the great unfed populace of the city. Taxation fell heavily and unjustly upon the people. The method of raising taxes by farming them out was a pernicious system that led to gross abuse. All enterprise and all investments were discouraged. There was no inducement for men to enter business, as labor had been dishonored and industry crippled. The great body of Roman people were divided into two classes, those who formed the lower classes of laborers and those who had concentrated the wealth of the country in their own hands and held the power of the nation in their own control. The mainstay of the nation had fallen with the disappearance of the sterling middle class. The lower classes were reduced to a mob by the unjust and unsympathetic treatment received at the hands of the governing class. In the civil administration there was a division of citizens into two classes: those who had influence in the local affairs of their towns or neighborhood, and those who were simply interested in the central organization. During the days of the republic these people were closely related, because all citizens were forced to come to Rome in order to have a voice in the political interests of the government. But during the empire {266} there came about a change, and the citizens of a distant province were interested only in the management of their own local affairs and lost their interest in the general government, so that when the central government weakened there was a tendency for the local interests to destroy the central.
