According to a groundbreaking new working paper by Carter C. Price and Kathryn Edwards of the RAND Corporation, had the more equitable income distributions of the three decades following World War II (1945 through 1974) merely held steady, the aggregate annual income of Americans earning below the 90th percentile would have been $2.5 trillion higher in the year 2018 alone.

Price and Edwards calculate that the cumulative tab for our four-decade-long experiment in radical inequality had grown to over $47 trillion from 1975 through 2018. At a recent pace of about $2.5 trillion a year, that number we estimate crossed the $50 trillion mark by early 2020.

The gap between the super-rich and the poorest half of the global population is starker than previously thought, with just eight men, from Bill Gates to Michael Bloomberg, owning as much wealth as 3.6 billion people, according to an analysis by Oxfam released Monday.

Presenting its findings on the dawn of the annual gathering of the global political and business elites in the Swiss ski resort of Davos, anti-poverty organization Oxfam says the gap between the very rich and poor is far greater than just a year ago. It’s urging leaders to do more than pay lip-service to the problem.

Drugs money worth billions of dollars kept the financial system afloat at the height of the global crisis, the United Nations’ drugs and crime tsar has told the Observer.

Antonio Maria Costa, head of the UN Office on Drugs and Crime, said he has seen evidence that the proceeds of organised crime were “the only liquid investment capital” available to some banks on the brink of collapse last year. He said that a majority of the $352bn (£216bn) of drugs profits was absorbed into the economic system as a result.

But I am concerned that the size of some of these institutions becomes so large that it does become difficult for us to prosecute them when we are hit with indications that if you do prosecute, if you do bring a criminal charge, it will have a negative impact on the national economy, perhaps even the world economy. And I think that is a function of the fact that some of these institutions have become too large.

Where Libor is set each day affects what families pay on their mortgages, the interest on savings accounts and returns on corporate bonds. Now, banks are facing a reckoning, as prosecutors make arrests, regulators impose fines and lawyers around the world file lawsuits claiming the manipulation pushed homeowners into poverty and deprived brokerage firms of profits.

“We will never know the amounts of money involved, but it has to be the biggest financial fraud of all time,” says Adrian Blundell-Wignall, a special adviser to the secretary-general of the Organization for Economic Cooperation and Development in Paris. “Libor is the basis for calculating practically every derivative known to man.”
