It is plain that all these expedients might perhaps in some respects mitigate, but could not remove, the existing economic disorders. The continuance of the distress is shown by the appointment of a bank-commission to regulate the relations of credit and to provide advances from the state-chest in 402, by the fixing of legal payment by instalments in 407, and above all by the dangerous popular insurrection about 467, when the people, unable to obtain new facilities for the payment of debts, marched out to the Janiculum, and nothing but a seasonable attack by external enemies, and the concessions contained in the Hortensian law,(10) restored peace to the community.

It is, however, very unjust to reproach these earnest attempts to check the impoverishment of the middle class with their inadequacy. The belief that it is useless to employ partial and palliative means against radical evils, because they only remedy them in part, is an article of faith never preached unsuccessfully by baseness to simplicity, but it is none the less absurd. On the contrary, we may ask whether the vile spirit of demagogism had not even thus early laid hold of this matter, and whether expedients were really needed so violent and dangerous as, for example, the deduction of the interest paid from the capital.
Our documents do not enable us to decide the question of right or wrong in the case. But we recognize clearly enough that the middle class of freeholders still continued economically in a perilous and critical position; that various endeavours were made by those in power to remedy it by prohibitory laws and by respites, but of course in vain; and that the aristocratic ruling class continued to be too weak in point of control over its members, and too much entangled in the selfish interests of its order, to relieve the middle class by the only effectual means at the disposal of the government--the entire and unreserved abolition of the system of occupying the state-lands--and by that course to free the government from the reproach of turning to its own advantage the oppressed position of the governed.
