Benefits and Costs of an Unequal Income Distribution

There are costs and benefits to unequal income distribution:

Benefits of unequal income distribution

Benefits of unequal income distribution

  • There are several benefits of unequal distributions:
    • Trickle down economics says that the poor may benefit from the success of the rich.
    • Unequal distributions can motivate some to work hard and can encourage entrepreneurship.
Costs of unequal income distribution

Costs of unequal income distribution

  • There are costs to unequal distributions:
    • They will increase levels of absolute and relative poverty.
    • If poverty is high, people may not be able to afford the basic needs, leading to increased levels of crime.
    • If some people have a very high income, depending on the marginal propensity to import, this could lead to a worsening of the balance of trade. If income rises, people will import more.

Inequality Between Nations

As well as inequality in income within a nation, different nations have different average incomes (GDP per capita).

Globalisation and deindustrialisation

Globalisation and deindustrialisation

  • The outsourcing of the manufacturing sector to developing nations created inequality in developed nations as the demand for manual and factory workers' skills fell drastically in the late 1900s.
  • However, GDP per capita growth in nations like China has benefited hugely from this change.
  • Although inequality in the USA has risen in recent years, in the last three decades, inequality between nations in the world has fallen.
Job creation or destruction

Job creation or destruction

  • Joseph Stiglitz (2018) argued that although many Western jobs were relocated to developing nations, jobs in developing nations were still destroyed faster than they were created.
  • Although people moved out of farming to work in higher 'value-add' industries like manufacturing, more people lost jobs than gained them.
  • The creation of jobs in the poorest developing countries may reduce the amount of people living in absolute poverty.
Capitalism

Capitalism

  • Capitalism relies on firms, individual incentives and the price mechanism to allocate resources.
  • Although this has led to economic growth, many people believe that government policies to manage inequality between nations and within nations is needed.
  • The UK allocates 0.7% of Gross National Income towards foreign aid.
