I think it is important to keep bringing up the idea of poverty in absolute terms. I have seen people living in poverty--I mean sitting in rags in the dirt with flies buzzing poverty--in other countries. It hurts to see. And yes, I am sure it exists here as well. And it is painful to see young kids pandering on the streets (and figuring that their existance is actually a step up from the abusive situation they may have come from). But it is different. And they do have access to healthcare--emergency rooms turn away no one due to ability to pay.
Again, I am not trying to trivialize a problem that clearly exists here. But I don't think trying to "Prove" how horrible America is compared to other countries helps anyone more forward with solving this problem.
