It's because we [benevolent and altruistic humanitarians] can't trust them [poor, under-developed] to know what to do with the money we give them. After all, they just loot. And since *we* know better how to use resources, we can make sure the "deserving" Haitians get help. Since children are the most "deserving" it's best that *we* control how resources are distributed to them, and that includes bringing them to us. How else can we control and ensure that our resources go to the most innocent and deserving? Even before the earthquake, they had tons of poverty in their country, and thousands of kids were being cared for in orphanages. Isn't it better for these poor, deserving children to come to the U.S. where we don't have poverty and children living in government care (i.e. foster care)? Oh, well, oops on the last statement. I mean, all we're trying to do is give these children a better life and keep them safe!
[Standard disclaimer here, since I know some will object: not ALL people, I didn't even say ADOPTIVE PARENTS, and I'm not referring to those children who were already assigned to adoptive parents.]
