This editorial in the WSJ points out the dangers to the Republican party in taking the stand on immigraton along the lines suggested by Donald Trump in August 2015- deportation for all illegal immigrants, no birthright citizenship for children of illegal immigrants, and no remittances allowed for illegal immigrants to their home countries. It points out that remittances actually improve the economies of the countries south of the U.S. border in Latin America and reduce illegal immigration. There is a need for seasonal workers in farm areas where there is a severe shortage of workers even at $17 an hour. Reducing immigration is better accomplished by more guest worker programs.
