The market economy is efficient, but not fair. Since wages are dictated by the law of scarcity, some people cannot earn enough to adequately live off their income. That is why a counterbalancing welfare state is needed to make net incomes fairer than if they were to be dictated by the market alone.
State redistribution can be interpreted as a form of insurance that protects citizens and their children from life’s trials and tribulations in a way that private insurance policies cannot. That is the basic justification for the welfare state.
However, state protection can lead to changes in behaviour, and can specifically weaken the efforts made by its citizens to secure an income. This reduces the size of the cake to be distributed. The art of economic policy is to strike best possible compromise between the size of the cake and the equality of its distribution.
