The cost of inequality - OXFAM report

This report is worth to read! How rapidly growing extreme wealth and inequality are harmful to human progress.
We know a lot about the subject, but there are some number which makes you really really sad and angry...

For example this:
"The top 100 billionaires added $240 billion to their wealth in 2012- enough to
end world poverty four times over."

Or this:
Over the last thirty years inequality has grown dramatically in many countries. In the US the share of national income going to the top 1% has doubled since 1980 from 10 to 20%. For the top 0.01% it has quadrupled to levels never seen before. At a global level, the top 1% (60 million
people), and particularly the even more select few in the top 0.01% (600,000 individuals - there are around 1200 billionaires in the world), the last thirty years has been an incredible feeding frenzy.
