Most countries, and Western countries in particular, are experiencing the demographic ageing that results from increased life expectancy and/or decreased fertility rates. This trend poses a challenge for societies on many levels. First of all, the share of the population who are in the active workforce will decrease under the current retirement legislation. This leads to a projected increase in dependency ratio in Europe from 42 retirees above 65 years per 100 workers to 65 in 2060 (Samuel, 2016).
