There are homeless everywhere in the world, even in the most advanced so-called democracy. Sadly enough the gap between the rich and the poor people is widening and it is a process that is almost unstoppable, especially with the financial crisis that since 2008 has left an high number countries almost in bankrupt.
Factories have closed down, workers are fired and the unemployment rate has reached an unthinkable level. In my Industrial Reverse Engineering project in 2013 I even found this huge space, formally an exhibition center, inhabited by the homeless that organised a little village. I heard that since than the police moved them out, to where nobody knows, they don’t have a house!!
