Poverty affects education
Regarding the July 19 online article “US wins Math Olympiad for first time in 21 years. Is math education improving?” (CSMonitor.com): The United States won the Math Olympiad, but American educators just can’t win. The Monitor’s report of the Olympiad reminded readers that US math scores are not at the top of the world rankings. The article then presented suggestions for improvement in math education. We are always interested in improving our teaching methods, but pedagogy is not the main problem. The main problem is poverty. Study after study shows that when we control for the effects of poverty, American academic performance, including performance on math tests, is among the best in the world. The best teaching in the world will not help when students are hungry, ill, and have little or no access to books.

The crime of being poor
Regarding the July 17 online article “Sandra Bland: Who was she, and what happened to her in a Texas jail?” (CSMonitor.com): It would be very interesting, in light of the heightened attention to and racial atmosphere surrounding the recent deaths of civilians at the hands of police, to investigate the income levels of all persons killed by police in the US over the past year as opposed to their race. I suggest that being black or Hispanic in America may not be nearly as heinous a crime as being poor.

Unfair comparison
In the June 29 cover story, “Where police don’t pull guns,” the writer attempts to compare countries such as Germany and America in the context of crime. On the surface this may seem to be a logical comparison, but looking deeper we see that America and Germany are as different as apples and oranges. Germany has a largely homogeneous society, while in America we have a diverse society that is growing ever more diverse.
