It reflects the contradictions that underpin what the right incorrectly believes about the issue of immigration. It is part of the pattern of demonizing immigrants, both those who are legal and those who are undocumented.
It is factually false in BOTH versions in the graphic.
Immigrants are not stealing jobs from Americans, in fact they provide much labor that would go unperformed otherwise. And immigrants are not lazy; they want to work, and indeed BOTH legal AND undocumented immigrants start up new businesses at twice the rate of American citizens, AND they pay a significant amount of taxes, including into social security (which they cannot collect from).
While coming to this country benefits those who do so, often those people are fleeing hellish conditions, it is still a less than desirable life to live in the shadows. We NEED immigration reform. We should be treating these people with compassion (except for those who are criminals like those who willingly - as distinct from unwillingly through coercion - work for drug cartels etc.).
As with the famous Bible quote (John 8:32) about the truth setting you free, the truth, the FACTS, about immigration and why it is GOOD for the United States could set a lot of people free - not only the immigrants themselves, but those who harbor ill will towards them without legitimate foundation to do so.
Because the issue of immigration is so central to the political right wing in 2015 and 2016 elections, it is imperative that we correct the misinformation and propaganda deception of the right wing voters with solid facts and effective persuasion. Not doing so, successfully, will harm all of us, not just the right, not just immigrants, but ALL of us, as a nation.
It won't be easy to do, but it is important to do. Please, start with sharing this. Hopefully the Schrodinger reference will be understood and the humor will help be persuasive, when put so graphically.
