1 Introduction
2 Conceptual Framework
Equality can be based on income, wealth, consumption or any other reasonable proxy for well-being (such as job opportunities and social security). Most of the empirical research focuses on inequality of annual income, because data for other types of inequality are less available and less measurable (Verme 2011; Piketty 2014). Income inequality is also important for many other dimensions of human well-being (e.g. education, health, etc.). In this paper we therefore focus on income inequality within countries.The real question is not whether the market economy works or not. It is whether it works the way we want it to work. Tomas Sedlacek (2012: page 319)
