Finland has become the first country in the world to pay a basic income to randomly picked citizens on a national level. The aim of 2-year nationwide pilot scheme is to reduce poverty, motivate people to join work force and boost employment. For this, two thousand unemployed participants between the ages of 25 and 58 have been randomly picked from different parts of the country and will receive an unconditional monthly tax-free basic income of €560. The income will replace their existing social benefits and will be paid even if they find work.
