For Americans concerned about Mexico and Mexicans, and what sort of wights they be, a little history may help. We seem to know almost nothing about a bordering nation of 130 million. It is not what most of us think it is. It is certainly not what the Loon Right would have us believe.
For many years, until 1910, Mexico was run by Europeans, lastly under Porfirio Diaz, for the benefit of Europeans. Literacy was extremely with economic conditions to match. The country was indeed, to borrow a favorite phrase of those hostile to Latin Americans, a Third-World hellhole. Many nations then were, to include China.
In 1910 the Revolution broke out. It was godawful, as civil wars usually are. It ended in 1921, followed shortly by the Cristero religious war until 1929. This had the usual hideousness favored by religious wars.
It left the country devastated. It hadn't been much to start with, but now it was a wreck. Aldous Huxley, writing in 1934, saw no improvement. (Beyond the Mexique Bay) At least until 1940 much of Mexico was barely civilized, unlettered, lawless, and poor. Things were not all that swell in 1970.
Today, seventy-six years later (says the CIA Factbook), literacy is at 95%; the economy at $2.2 trillion, 12th in the world in PPP; median age, 28; population growth rate, 1.12%; mother's mean age at first birth, 21.3; total fertility, 2.24 children per woman; life expectancy at birth, 76 years.
And of course internet, airlines, computerized everything, and teenagers pecking at smartphones.
This is a lot of change in less than a man's lifetime. Those hostile to Latin Americans do not want to know this, and usually manage not to.
