On the federal level, the poverty threshold for a family of five makes up $28,410, although 51% of all American workers make less than $ 30,000 a year at the moment...According to the US Census Bureau, nearly 47 million Americans live in poverty right now. In 2007, approximately one out of every eight children in the US was receiving food stamps. Today, the index has grown to one of every five. Experts point out that there are 1.5 million households in the United States that live on less than two dollars a day. This number has doubled since 1996. Forty-six million Americans use food banks each year. The number of homeless children in the United States has increased by 60 percent in the last six years.
