From Yale Review of "Exploited-Migrant Labour in the New Economy"

"Governments of the wealthiest nations have created multiple dilemmas for their countries, their workers, the migrants and democracy itself.
.....
Citizens in wealthy nations are divided between those who want to close the gates on immigration and those who welcome the newcomers
....
the ambitions poor in this unequal world are willing to risk their lives to improve their lot.  Haphazard enforcement...[does] little to dissuade job-seekers...anticipating tedious, revolting and even dangerous work.
...such immigrants hope that their sacrifice is temporary...jobs mean survival in the modern world....  Ordinary citizens can only witness the rising inequality an degrading values that accompany a 2-tier class society.  Governments easily claim that the newcomers from other countries have no rights so the immigrants become a convenient foe...

Employers large and small take advantage of undocumented workers willing to work for low wages and yet the wealthy respond as though their communities were under attack by those who flee poverty in their homelands.  That attitude suggests that the workers don't mind the exploitation."
