Why do borders matter? Here's our show: EUROPE'S REFUGEES: What will Europe do about the thousands of Syrian refugees? Did America cause the crisis by going into Iraq? BORDER WARS: Most presidential candidates say "seal the border!" What's possible? Who is right? STATE BORDER: We assume there's something natural about borders between countries and states, but some division are insane. Part of Idaho is in Montana because a legislator got drunk. Part of Kentucky is in Tennessee because iron ore confused surveyors' compasses. Utah was made smaller because the U.S government hated polygamy. STATES' RIGHTS: States are often called "laboratories of democracy" because they allow experiments. States are doing that now with issues like marijuana and school choice. With gay marriage, however, The Supreme Court said that states must be told what to do. OPEN BORDERS?: Jeffrey Tucker of Laissez Faire Books argues that we should have NO border controls. That was the law in America until the Immigration Act of 1882 banned "idiots, lunatics, convicts and persons likely to become a public charge." Stossel and Tucker debate. MY TAKE: The border would be easier to secure if America were not also fighting a drug war. The War on Drugs has destroyed entire parts of Latin America and provided funds to the smugglers who sneak people North. If there were a clear benefit to the drug war, you might say it was worth it. Instead, it yields death, dislocation of populations, and funds murderous cartels that dig tunnels beneath our border walls.
