Liberals frequently cite international law when they seek to have SCOTUS veer from precedence. Similarly, liberals have plumped for Europeanization of the United States. [How is Europe doing, btw?] On the question of legal immigration, liberals are nowhere to be found citing other country's rules or international law. Japan, e.g., permits no legal immigration; China returns illegals to North Korea and the Europeans allow few other than from present or former colonies. There is substantial illegal immigration into the major European countries, not so much, say, into Norway, Finland, Latvia, Poland or Italy. Let's look at some undeniable facts about legal immigraton into the United States:
1. In 2009, the United States issued over 1.1 million green cards, more residency permits than all the other countries of the world combined.
2. From 2000 through 2009, the United States issued over 10 million green cards.
3. In 2008, the United States issued 920,000 temporary work permits in addition to the green cards issued that year.
4. More than one of every eight persons you see in America is a non-citizen immigrant.
5. 92% of the green card holders are people without special skills, a college education or financial resources.
Add to these numbers, the illegal immigrants and you begin to see one major reason for the unraveling of the American economy: too many immigrants displacing citizens from employment. The best jobs bill for Obama to pass would be a moratorium on legal immigration and, when re-opening the Golden Door, to admit far fewer people, especially those without skills, education or money.
The statistics cited are from data released by the Department of Homeland Security. If you have any doubts, you could look it up.
