Here is an interesting article from the NYT: For Migrants and the Poor, Tents Must Count as Homes
This is happening in France, but I wonder how long until it happens in the United States. We have the poor and homeless, but a rising epidemic is taking place known as the "working poor." These are the people who have jobs, want employment, but can't seem to makes ends meet each month. Becuase they can't make ends meet, they do without in some pretty vital areas; particularly health care and dental.
I see this as part of the church's call to minister to the poor, the widow, and the orphan.
