People living in extreme poverty was not all that uncommon in the wealthiest nations until recently, the World Bank reports. In most of today's richest nations, the majority of the population lived in some level of poverty just a few generations ago. The rapid progress is due to improvements in medicine and the economy, among other factors.Despite making impressive strides towards pulling people out of poverty, many of today's wealthiest nations still have some fraction of their populations living in extreme poverty.
