The major examples of social inequality include income gap, gender inequality, health care, and social class. In health care, some individuals receive better and more professional care compared to others. They are also expected to pay more for these services. Democracy has a significant and robust effect on redistribution, but it fails to reduce inequality. ... Thus, the benefits of any redistributive policy accrue more to the middle class than the poor, and as a result, income inequality may not decline as expected (see also Stigler 1970).

Every political party has a number of functions to perform. Here we have listed some of them.
- A political party contests elections by putting up candidates.
- In countries like the USA, the candidates are selected by members and supporters of a party.
- On the other hand, in countries like India, the candidates are chosen by top party leaders.
- Every party has different policies and programmes. Voters make a choice in accordance with the policies and programmes liked by them.
- In a democratic country, a large group of people that has certain similar opinions group together and form a party. Then then, give a direction to the policies adopted by the government.
- Those parties which lose elections form the opposition. They voice different views and criticise the government for their failures and mobilize opposition to the government.
