United States Planning To Toughen Mexican Border Control The United States is planning to amp up security along it's border with Mexico. The Obama administration says that, among other reasons, heightened border security will help protect some of the country's southern states from the dangerous drug wars that have been going on south of the border and spilling into the U.S. from time to time. However there may be a second, more economically geared, reason. With a struggling economy the United States can't support many new illegal, or legal, immigrants. The new controls are sure to stunt the influx of illegal workers, which for now could be a good thing for American business.
