People in countries where income is protected report high levels of happiness, but about three quarters of the world’s workers live in circumstances of economic insecurity that foster ‘a world full of anxiety and anger,’ according to a new United Nations study. Only 8 per cent of people - fewer than one in 10 - live in countries providing favourable economic security, according to the survey produced by the International Labour Organization (ILO). A socio-economic safety net, rather than income level, not only promotes personal well-being, happiness and tolerance but also benefits growth, development and social stability, it says.
