Opponents also typically insist that undocumented immigrants lower wages and labor standards by offering their cheap labor and by being willing to work under very harsh conditions (“Lower wages,” 2008). This, increases unemployment and affects the living conditions of the working class and poor Americans (“Amnesty,” 2009). Thus, according to opponents, a comprehensive immigration reform would reward “criminals” who, not only broke the law, but also exploit the US economy, degenerate society, and compete against natives for work opportunities that are running scarcer as more people continue to come to the US. Legalizing the millions of undocumented immigrants that currently reside in the US would send future immigrants the wrong message that it is acceptable to enter the US illegally and that they will, in the future, be similarly forgiven (“What is wrong,” 2005). Finally opponents complain that legalizing undocumented immigrants would be very unjust for both, those that went through the long, legal process of receiving a visa, and for those that are still waiting to receive one.
