"The immigration problem" or "the border problem" has been a heated topic of debate and politicking in recent years. (This recent spurt is only the most recent in a series that goes back for centuries in U.S. history.) In large part this debate pertains to the entry of Mexicans, especially undocumented Mexicans, into the USA. For those who support a strong "closed borders" or "secure the border" position, the debate often involves claims about Mexicans—what sort of people they are, what one may reasonably expect them to do if they become residents of the USA, what crimes they have committed or will commit in the future, and so forth. Anyone who is familiar with Mexicans is struck repeatedly by the sheer ignorance and the false claims that immigration opponents marshal in support of their position. The president himself has trotted out howlers about Mexican rapists and drug traffickers as important, standing problems of even the existing flow of Mexicans into the USA.
I have a working familiarity with the social science literature on immigration. (In the past I have written articles for economic history and demography journals that dealt with various aspects of immigration in the late nineteenth and early twentieth centuries.) More to the point for present purposes, I have considerable personal experience with Mexicans. I grew up on the rural west side of California's San Joaquin Valley in the 1950s in a place with a population composed of about two-thirds Mexicans and their native-born children. In October 2015, I emigrated from the USA, and since then I have lived in the Mexican state of Quintana Roo. I speak Spanish, though not with the fluency I would like, and in one way or another I deal with Mexicans nearly every day. So when I think or speak about Mexicans I do so with some personal as well as scholarly background.
In this light, I am stunned by how many Americans have a false impression of Mexicans. Of course, any generalization about them will be subject to qualifications. Mexico is a large, diverse country with a large, diverse population. And obviously from individual to individual great variations exist. No population consists of nothing but good people (however defined) or nothing but bad people (however defined).
Overall, I have found Mexicans—both those with whom I grew up in California and those among whom I now reside in Mexico—on average to be fine people in all relevant dimensions. They are devoted to their families and love their children. They are extremely hard workers, often under extraordinarily difficult and unpleasant conditions. They are good-natured and friendly, courteous and generous. They are also in many cases surprisingly resourceful, knowing how to build or repair all sorts of things, often without proper tools or materials. Many of them have an artistic capacity that allows them to create various products that are not only practical but also beautiful. Centuries of oppression and brutality by the ruling classes have not destroyed their hope for a better future, and they are often willing to bear great personal costs in order to make that future better for themselves and their children.
