1840-1850: Census documentation of declining Tejanx economic position
The 1840 census of the Republic of Texas recorded him as holding one town lot in San Antonio, presumably the location of his private residence, and two horses. He was also the agent of record for his widowed mother, who owned one town lot. After U.S. annexation of Texas, his level of prosperity remained relatively constant. In 1840, on the first U.S. census conducted in San Antonio, he was listed as a “merchant” who owned real estate valued at $2,000; a newspaper report from seven years later mentions Menchaca as one owner of transport carts loaded with goods that left San Antonio for the coast under armed guard during the infamous Cart War.
 Still, in comparison to other San Antonio Tejanos, Menchaca’s retention of his homestead and mercantile interests placed him ahead of many contemporaries. Although incomplete, the census of 1840 showed that Tejanos owned 85.1 percent of the town lots in San Antonio, along with 63.8 percent of all land acreage titled to local residents. According to the 1850 census, they owned only 9.1 percent of real estate values claimed. Similarly, in 1830, when Tejanos comprised nearly all the population of San Antonio, the census showed that most residents were farmers and only 14.8 percent were laborers. No employment listings were given in the 1840 census, but in 1850, 61.4 percent of the Tejano population was in labor positions. Menchaca was comparatively well off, but only in relation to a San Antonio Tejano population undergoing a significant downward trend in economic status from landowners to a working underclass.
Menchaca did not complacently accept the woes of his fellow Tejanos. He was a frequent witness for Tejano parties in court cases, particularly for veterans seeking the compensation due them by law for military service in the Texas Revolution. Convinced that the just claims of many Tejano veterans had been denied or unduly delayed as compared to the more prompt approvals their Anglo-American counterparts received, Menchaca was one of nineteen Tejano signers in 1875 of a letter to the Texas comptroller of  public accounts that sought to “disabuse [Comptroller Stephen H. Darden’s mind of any prejudice” against Tejano veterans and that demanded for themselves and their comrades “simply justice and nothing more.” His support of fellow Tejanos was so strong that apparently he did not even hold grudges against those who supported the Mexican side in the Texas Revolution. For example, he provided a deposition to support the legal claims of Francisco Esparza, a San Antonio native who, unlike his Alamo-defender brother Gregorio, had opted to fight in the Mexican army during the December 1835 Texan siege of San Antonio and was on reserve with the Mexican forces during Santa Anna’s Texas campaign. James Newcomb summed up Menchaca’s leading role as a legal advocate when he quipped that “in later years, when the titles to almost every foot of ground in the old city and county of Bexar were litigated in the courts, Captain Menchaca became a standing witness to prove up the genealogy of the old families.”

The downward trend in socioeconomic fortunes of Bexareños was not unique, either to Texas or to the Southwest generally. Arnoldo De León, in The Tejano Community, 1836-1900, was the first to explore this theme in a major work, not from the perspective of victimization, but from that of resistance and self-assertion. David Montejano, in confirming De León’s findings, expanded the focus to include the legalistic dynamics of Tejano marginalization in the nineteenth century in Anglos and Mexicans in the Making of Texas, 1836-1986. Beyond Texas, Richard Griswold del Castillo, in The Los Angeles Barrio, 1850-1890: A Social History, and Albert Camarillo, in Chicanos in a Changing Society: From Mexican Pueblos to American Barrios in Santa Barbara and Southern California, 1848-1930, trace the very similar processes at work in southern California during the nineteenth century. Even in New Mexico, where they remained such a large percentage of the population, Laura E. Gómez demonstrates in Manifest Destinies: The Making of the Mexican American Race that Mexican Americans faced socioeconomic decline. In all these cases, the result was the formation and reinforcement of a distinctly Mexican-based identity.↩
