The difference between wages is getting bigger in almost all leading economies in the world, according to OECD. The survey researched 22 countries and indicated that the wage inequality between reach and poor essentially increased in 17 of these countries. The most unequal countries are Chile, Mexico, Turkey and the United States. Even in more egalitarian nations like Germany, Denmark and Sweden the gap is widening. On average 10% of the richest part of the population has nine times higher wages than poorest, reported OECD.
