All the money in the world is growing ever more concentrated in the hands of just a few people, a report released Sunday night makes clear.<br />Just 62 ultra-rich individuals -- a list that is primarily made up of men and includes Bill Gates, Warren Buffett, the Koch Brothers and the Walmart heirs -- have as much wealth as the bottom half of humanity.<br />Five years ago, it took 388 rich guys to achieve that status.<br />The wealth of the richest 62 has increased an astonishing 44 percent since 2010, to $1.76 trillion.<br />Meanwhile, the wealth of the bottom half of the world dropped by 41 percent.<br />Rising wealth and income inequality is not simply an issue of fairness or social justice or economic growth.<br />Oxfam's report also points a finger at tax dodging and urges governments worldwide to get a handle on tax avoidance by wealthy individuals and corporations.
