The Biden-Harris experiment in dissolving the U.S. border has wrought massive changes to American society, most of which will not be understood for years, if not decades. Since 2021, U.S. border officials have had at least 10 million "encounters" with migrants, many of whom were allowed to enter the country. There is no telling how many more aliens entered the country without encountering enforcement agents. The population of the United States may have increased by as much as 15 million people in just a few years.
