Unless you have been in a coma the last year, you know that the economic, credit, housing, foreclosure crisis has wreak serious havoc on many people. It is almost "just news" to read about former middle class people now having to live in their car or tent cities that seem to spring up everywhere. However, this crisis has spread globally and the poor in Third World countries are now even more impoverished. Instead of living on $3 a day, they live on $1 a day.
I was born in a Third World country. The nuns in school used to take us on field trips to visit the squatter areas. There, families built makeshift homes of cardboard and whatever scraps they could find. These houses were put together (constructed is not the right word) one on top of the other, and usually over sewage canals. Whenever there was a storm that caused a flood, these little houses would be washed away, sometimes carrying the occupants with it.
It is a very serious problem. I wonder if it will ever be solved in my lifetime.
