According to a Guardian report "Income inequality has increased and social mobility stalled across the world’s richest countries since the 1990s, trapping families on low incomes at the bottom of the earnings ladder, according to an in-depth report by the Organisation for Economic Co-operation and Development.
In the UK the report found it could take at least five generations, or 150 years, for the child of a poor family to reach the average national income, currently about £27,000 for those in full-time employment, compared with two generations in Denmark and three in Sweden."

The number of children living in poverty will soar to a record 5.2 million over the next five years as government welfare cuts bite deepest on households with young families.
