What even serious individuals must note is that 40 or 50 years ago, the kind of jobs that illegal immigrants migrate towards today are the same positions that African Americans were relegated to. How else can we explain highly educated African Americans, even some with Ph.D's, being forced to work at the post office or as a hotel waiter. The barriers for African Americans were Jim Crow; for Hispanics or Latinos fleeing Mexico, El Salvador, Guatamala or other South American countries, it is the wretched poverty in those countries. For them, such jobs are a "step up" from what they had to accept in their country.
