John Hinderaker has two alternate theories:
…[T]he Obama administration is actively recruiting indigent foreigners to come to the United States to receive welfare benefits. Its Welcome to USA.gov page is largely about the welfare benefits that new immigrants can receive. The administration has even partnered with the government of Mexico to advertise the availability of food stamps to Mexican immigrants (including, although this is not officially stated, illegals). In part because of the Obama administration’s recruitment, the number of non-citizens receiving food stamps has quadrupled since 2001, to an estimated 1,634,000 as of June 2012…
If we assume that the administration’s goal is to maintain the United States as a strong and prosperous nation, then its immigration policies are quite literally insane. I can see only two possible explanations for the administration’s eagerness to attract welfare recipients from other countries. One is that Obama is so blinkered by ideology that he irrationally believes that any expansion of government spending must necessarily be a good thing. The other is that his objective is not, in fact, to preserve America as a strong and prosperous nation.
And I have two words in response (or maybe it’s one, since it’s hyphenated): Cloward-Piven.
And then there’s the fact that the vast majority of these voters probably will vote the Democratic ticket some day, and/or their American-born children will. It’s really a win-win situation for the left, isn’t it?
And yes, I’m very cynical. But, I think, rightly so. There’s really (as Hinderaker suggests) no other logical explanation.
