The end to extreme poverty might very well be within reach. But is the bar too low?
The World Bank aims to raise just about everyone on Earth above the $1.25-a-day income threshold. In Zambia, an average person living in such dire poverty might be able to afford, on a given day, two or three plates of cornmeal porridge, a tomato, a mango, a spoonful each of oil and sugar, a bit of chicken or fish, maybe a handful of nuts. But he would have just pocket change to spend on transportation, housing, education and everything else.
