Classical ideas of citizenship centered around civil, political, and social rights as defined by T.H. Marshall. However, citizenship has been critiqued for excluding and degrading parts of humanity. While Australia portrayed itself as a classless society based on displacement, inequality has always existed and the myth of egalitarianism has been challenged. Studies by Wilkinson and Piketty show that greater inequality negatively impacts societies and that inequality will likely worsen as the rich accumulate wealth faster than economic growth. This raises questions around who benefits from poverty and inequality, what role the state should play in alleviating it, and the limits of rights-based citizenship in including all groups.
