This is absolutely beyond the pale, and it is not "sustainable" in any kind of society:
The world’s richest 85 people control the same amount of wealth as half the world’s population, according to a report issued Monday by the British-based anti-poverty charity Oxfam.
That means the world’s poorest 3.55 billion people must live on what the richest 85 possess. Another way to look at it: Each of the wealthiest 85 has access to the same resources as do about 42 million of the world’s poor, a number equal to the populations of Canada, Kentucky and Kansas, taken together.
The report was issued just before The World Economic Forum opens on Wednesday in Davos, Switzerland. The forum is a gathering spot for world political, academic and business leaders where, the forum’s website says, they “shape global, regional and industry agendas."
In announcing the study, Oxfam’s website said that what it sees as the growing wealth gap undermines democracy.
Criticizing this criminal class isn't a case of "envy," by the way, for this is a matter of sociopaths gaming the system in an insatiable pursuit of greed. It is all THEFT.
