Possessed of money and influence, it was not hard for a senator to outwit mere _curiales_, either by obtaining an exemption from the Emperor, or by bribing the occasional inspectors sent by the central government to condone his refusal to pay. The imperial court set an example of corruption, and those who could imitate this example did so. The _curiales_, faced by ruin, sought relief in various ways. Those with most wealth tried to raise themselves to senatorial rank: others, unable to achieve this, yet conscious that they must obtain the money required at all costs, demanded the heaviest taxes from those who could not resist them, so that the phrase spread abroad, ‘So many _curiales_ just so many robbers.’ Less important members of the middle classes, unable to pay their share of taxation or to force others to do so instead, tried in every way to divest themselves of an honour grown intolerable, and the legislation of the later Empire shows their efforts to escape out of the net in which the government tried to hold them enmeshed. Some sought the protection of the nearest landowners, and joined the dependants of their ‘villas’: others, though forbidden by law, entered the army: while others again sold themselves into slavery, since a master’s self-interest would at least secure them food and clothing. More desperate and adventurous spirits saw in brigandage a means both of livelihood and of revenge. Joining themselves to bands of criminals and escaped slaves, they infested the high roads, waylaid and robbed travellers, and carried off their spoils to mountain fastnesses. Thus, through fraud or violence, the ranks of the _curiales_ diminished, and taxation fell with still heavier pressure on those who remained to support its burdens. This evil state of affairs was intensified by the widespread system of slavery that, besides its bad influence on the character of both master and slave, had other economic defects. When forced labour and free work side by side, the former will nearly always drive the latter out of the market, because it can be provided more cheaply. A master need not pay his slaves wages; he can make them work as many hours as he chooses, and lodge and feed them just as he pleases. From his point of view it is more convenient to employ men who cannot leave his service however much they dislike the work and conditions. For these reasons business and trade tended to fall into the hands of wealthy slave-owners who could undersell the employers of free labour, and as the number of slaves increased the number of free workmen grew less. In Rome, and the large towns also, free labourers who remained were corrupted like men and women of a higher rank by the general extravagance and love of pleasure. They did not agitate so much for a reform of taxation or the abolition of slavery, but for larger supplies of free corn and more frequent public games and spectacles.
