Well, my tongue in cheek suggestion based on Jonathan Swift’s “A Modest Proposal” appears to be a growing statistic. According to the Arizona Republic, smuggling small children is a growing business in border areas. The frequency of smuggling small children has increased to the point where “[t]he U.S. Attorney's Office was so alarmed by the trend that in March 2007, the agency announced a concerted effort to pursue the harshest penalties for suspected child smugglers. Sentences since then have averaged about 15 months in federal prison.”
Still from a cost benefit anaylsis, 15 months versus years for drug smuggling, smuggling babies in trikes still makes this a viable alternative.
