    “…While the results of these indices have been found to vary in the details, they all point in a similar direction: most industrialised countries are imposing increasing burdens on younger and future generations, as is evidenced, for example, by their high sovereign debts, youth unemployment and poverty, and perennial ecological crises. In a 2013 study published by the Bertelsmann Foundation, and led by Pieter Vanhuysse of the UN’s European Centre for Social Welfare Policy and Research, a total of 29 OECD states were compared on the basis of four indicators: public debt per child; the ecological footprint created by all generations currently alive; the ratio of child- to elderly-poverty; and the distribution of social spending among generations (“elderly-bias indicator of social spending”, EBiSS). …”
