Can't really find the article but the right has similar problems. In the war of terror a live is valued at about 200 million USD, while on every other life protecting service like fire department or police it is about 10 million. So the war on terror is effectivly killing our own population by consuming funds that could be used better.
And I don't even know why the left, who had tight border patrols in the cold war, is now the pro immigration camp. I love other cultures, but that is more of a personal taste, and even I think that immigration is out of control and often done in a very unsocial way.
