James R. Rogers enumerates the costs and benefits of economic globalization :

The source of increasing inequality in the U.S. also can be a source of decreasing inequality in less-developed countries as workers earn more and capital earns less. This complicates the morality of policies that seek to resist the effects of globalization. Protecting some American workers can mean impoverishing some overseas workers.

Bishop Samuel Aquila on Christian principles for immigration reform :

We need comprehensive immigration reform. If we undertake immigration reform in accord with natural law—in accord with truth—there are certain principles we should uphold.
