The gap between the poor and extremely rich is widening, and it's a troubling trend, according to a new report.
The annual Oxfam International report says the world's 62 richest people have the same amount of wealth as the bottom 50 percent of the world. For comparison, it took 80 billionaires last year to make up half the world's wealth. Further back in 2010, that number was 388.
According to the report, there's been a drastic change of the rich getting richer and the poor getting poorer. Since 2010, the wealth of the world's poorest has dropped by about $1 trillion, or 41 percent. The wealthiest have seen their riches rise by about $540 billion in that same time frame.
