Educação vs PNB na Europa

When you plot education and wealth in Europe, you always get a chart like this. Rich and educated countries in Q1, the educated but poor Eastern countries in Q2, and Club Med in Q3, with Portugal in a specially low position. You can see the impact of the economic crisis in several countries (I added markers to some of them to make it clearer), while the Eastern countries keep swimming towards a higher GDP per capita.

As mamãs solares - serão as mulheres melhores que os homens no esforço para saírem da pobreza?



Rafea is the second wife of a Bedouin husband. She is selected to attend the Barefoot College in India that takes uneducated middle-aged women from poor communities and trains them to become solar engineers. The college's 6-month programme brings together women from all over the world. Learning about electrical components and soldering without being able to read, write or understand English is the easy part. Witness Rafea's heroic efforts to pull herself and her family out of poverty.
