Yes indeed. The federal poverty level works out to about 15 dollars per day, per person. Eighty percent of the world gets by on under ten dollars a day.
When I was in Indonesia I made friends with a Balinese cab driver whom I had hired for a day to take me around Ubud. At the end of the day I paid him what we had agreed on in Rupiah, then tipped him a one dollar bill. He stared at it, wide-eyed, then looked at me with an expression of disbelief.
Then he said, simply, "thank you, my family will eat tonight."
Being poor in America ain't like being poor in other places.
