The Arizona immigration law prompted Seth Minkoff of Somerville, a professor at UMass Boston, to write a letter to the Boston Globe, titled ‘Illegal' immigrants have moral claim on US citizenship rights:

...some of us also feel that the fundamental aim of this law - enforcement of federal immigration regulations - is immoral.

A great many undocumented immigrants come here from countries that the United States has systematically devastated for generations by overthrowing democracy (as in Guatemala), sponsoring dictatorship and state terror (Guatemala, Nicaragua, El Salvador, and Haiti), and invading and annexing territory (Mexico). Actions such as these have helped the United States to control a grossly outsized share of world resources.

Until the US share of world resources is proportional to its population, so-called illegal immigrants will have a moral claim second to none on the rights of US citizenship. Arizona's new law, like the federal laws it seeks to enforce, is an assault on people's basic right to feed and clothe their families - in other words, on their right to access their fair share of the planet's wealth, the patrimony of humanity.
