The job tide has turned.
For decades...Brasil's citizen fled...seeking work elsewhere.
Now Brasileros are returning home...and many Portuguese, Spanish, Italians and Haitians are following them.
With unemployment at a record low...Brasil needs and attracts the skilled...and unskilled...forcing the government to deal with a new immigration challenge.
AND: Some protest Brasil's social inequalities even as it booms.
The ugly protests are visible throughout many parts of vast and wealthy Sao Paulo...where a kind of urban warfare is underway...as protesters paint many buildings...black.
ALSO: Brasil's lack of online entrepreneurs.
