Donald Trump has made building a wall with Mexico the centerpiece of his campaign. Yet America's attempt to build a wall under the Bush Administration has given us some idea about how much such an endeavor would cost.
The American and Mexican communities that live at the border are united by common geography, history, language, and aspirations, and have much to teach the rest of the country about how to build harmonious bicultural communities.
Would the construction of an 18-foot high concrete fence running the length of the border greatly disrupt the flow of illegal people, drugs, and weapons into the U.S.? Certainly. Will it be 100 percent effective? Certainly not.
Claiming that the main motivation of the children who flee the Northern Triangle is anything other than violence and danger is worse than false, because such claims try to absolve Americans of the responsibility for solving the crisis.
