Just to put it short

Globally, the richest eight people - including Microsoft founder Bill Gates and Facebook's Mark Zuckerberg - own as much as the poorest half of the world's population, or about 3.6 billion people.
Such an extreme divide between the rich and the rest risks plunging future generations into political instability, undermining our democratic institutions and creating economic upheaval

That is a data from U.N. Amen , no comment on that , you be the judge

Australia ? same crap .Australia's two richest people, Gina Rinehart and Harry Triguboff, own more than the poorest 20 per cent of the country's population
