This is an excellent source of latest research data on Income Distribution and Poverty, in both the developed and developing World, published by the OECD. It’s a STRONGLY RECOMMENDED READ, in my view. Check it out!
For me, it is striking, how since the financial crash of 2008, that inequality has increased on such a massive scale. The top 1%, the super-rich, have rebounded strongly and their wealth and incomes have increased enormously. Meanwhile, for the majority, the “great-unwashed”, things have been increasingly hard.
Of course, for the the lives of ordinary citizens of both the middle and lower classes, matters have been seriously aggravated by austerity policies followed in Washington, London and Berlin.
