I'm neither American, nor shocked at the idea that America has poverty. I am, however, a bit of a stickler actual information. Pointing to general issues does absolutely nothing to help source this claim.

The claim was that ~65M people were in "who live in the most abject poverty seen in the developed world."

The actual figure for a poverty measure is 43M. However, that's not what the claim was - it's not simply that people are in poverty but those that are are in "the most abject poverty seen in the developed world".

Either we can find actual information and have a real discussion, or we can throw around vague unsourced claims and get nowhere.
