US-Mexican relationship in the first three decades of 1900s. At the beginning of the 1900s the US Southwest was increasingly influenced by railroad networks, large scale mining, and comercial farming based on mass markets. The development of large scale business was paralleled by extensive labor organizing. The prosperity and economic boom was in large measure based on Mexican labor, however they were not well compensated. The prosperity was based on cheap labor at the expense of mexicanos and many other minorities groups in the form of low wages and poor working conditions. In way, cheap labor has subsidized US agriculture, mining, and many other industries.
