What if the U.S.-Mexico border went poof and nothing bad happened except the end of 160 years of misguided racist apartheid? 

The age-old pesky U.S.-Mexico border problem has taxed the resources of both countries, led to long lists of injustices, and appears to be heading only for worse troubles in the future. Guess what? The border problem can never be solved. Why? Because the border IS the problem! It's time for a paradigm change. Never fear, a satisfying, comprehensive solution is within reach: the Megamerge Dissolution Solution. Simply dissolve the border along with the failed Mexican government, and megamerge the two countries under U.S. law, with mass free 2-way migration eventually equalizing the development and opportunities permanently, with justice and without racism, and without threatening U.S. sovereignty or basic principles.
