Some one has remarked, and rightly, that Diaz in his zeal for the material advancement of Mexico, mistook the tangible wealth of the country for its welfare. Desirable and even necessary as that material progress was, it produced only a one-sided prosperity. Diaz was singularly deaf to the just complaints of the people of the laboring classes, who, as manufacturing and other industrial enterprises developed, were resolved to better their conditions. In the country at large the discontent was still stronger. Throughout many of the rural districts general advancement had been retarded because of the holding of huge areas of fertile land by a comparatively few rich families, who did little to improve it and were content with small returns from the labor of throngs of unskilled native cultivators. Wretchedly paid and housed, and toiling long hours, the workers lived like the serfs of medieval days or as their own ancestors did in colonial times. Ignorant, poverty-stricken, liable at any moment to be dispossessed of the tiny patch of ground on which they raised a few hills of corn or beans, most of them were naturally a simple, peaceful folk who, in spite of their misfortunes, might have gone on indefinitely with their drudgery in a hopeless apathetic fashion, unless their latent savage instincts happened to be aroused by drink and the prospect of plunder. On the other hand, the intelligent among them, knowing that in some of the northern States of the republic wages were higher and treatment fairer, felt a sense of wrong which, like that of the laboring class in the towns, was all the more dangerous because it was not allowed to find expression. Diaz thought that what Mexico required above everything else was the development of industrial efficiency and financial strength, assured by a maintenance of absolute order. Though disposed to do justice in individual cases, he would tolerate no class movements of any kind. Labor unions, strikes, and other efforts at lightening the burden of the workers he regarded as seditious and deserving of severe punishment. In order to attract capital from abroad as the best means of exploiting the vast resources of the country, he was willing to go to any length, it would seem, in guaranteeing protection. Small wonder, therefore, that the people who shared in none of the immediate advantages from that source should have muttered that Mexico was the "mother of foreigners and the stepmother of Mexicans." And, since so much of the capital came from the United States, the antiforeign sentiment singled Americans out for its particular dislike.
