Income inequality in the context of "Rent seeking"

Social inequality occurs when resources within a society are distributed unevenly, often as a result of inequitable allocation practices that create distinct unequal patterns based on socially defined categories of people. Differences in accessing social goods within society are influenced by factors like power, religion, kinship, prestige, race, ethnicity, gender, age, sexual orientation, intelligence and class. Social inequality usually implies the lack of equality of outcome, but may alternatively be conceptualized as a lack of equality in access to opportunity.

Social inequality is linked to economic inequality, usually described as the basis of the unequal distribution of income or wealth. Although the disciplines of economics and sociology generally use different theoretical approaches to examine and explain economic inequality, both fields are actively involved in researching this inequality. However, social and natural resources other than purely economic resources are also unevenly distributed in most societies and may contribute to social status. Norms of allocation can also affect the distribution of rights and privileges, social power, access to public goods such as education or the judicial system, adequate housing, transportation, credit and financial services such as banking and other social goods and services.

Economic inequality is an umbrella term for three concepts: income inequality, how the total sum of money paid to people is distributed among them; wealth inequality, how the total sum of wealth owned by people is distributed among the owners; and consumption inequality, how the total sum of money spent by people is distributed among the spenders. Each of these can be measured between two or more nations, within a single nation, or between and within sub-populations (such as within a low-income group, within a high-income group and between them, within an age group and between inter-generational groups, within a gender group and between them etc, either from one or from multiple nations).

Income inequality metrics are used for measuring income inequality, the Gini coefficient being a widely used one. Another type of measurement is the Inequality-adjusted Human Development Index, which is a statistic composite index that takes inequality into account. Important concepts of equality include equity, equality of outcome, and equality of opportunity.

Social mobility is the movement of individuals, families, households or other categories of people within or between social strata in a society. It is a change in social status relative to one's current social location within a given society. This movement occurs between layers or tiers in an open system of social stratification. Open stratification systems are those in which at least some value is given to achieved status characteristics in a society. The movement can be in a downward or upward direction. Markers for social mobility such as education and class, are used to predict, discuss and learn more about an individual or a group's mobility in society.

A market intervention is a policy or measure that modifies or interferes with a market, typically done in the form of state action, but also by philanthropic and political-action groups. Market interventions can be done for a number of reasons, including as an attempt to correct market failures, or more broadly to promote public interests or protect the interests of specific groups.

Economic interventions can be aimed at a variety of political or economic objectives, including but not limited to promoting economic growth, increasing employment, raising wages, raising or reducing prices, reducing income inequality, managing the money supply and interest rates, or increasing profits. A wide variety of tools can be used to achieve these aims, such as taxes or fines, state owned enterprises, subsidies, or regulations such as price floors and price ceilings.

Mexico has a developing mixed economy. It is the 13th largest in the world in nominal GDP terms and by purchasing power parity as of 2024. Since the 1994 crisis, administrations have improved the country's macroeconomic fundamentals. Mexico was not significantly influenced by the 2002 South American crisis and maintained positive, although low, rates of growth after a brief period of stagnation in 2001. However, Mexico was one of the Latin American nations most affected by the 2008 recession, with its gross domestic product contracting by more than 6% that year. Mexico has the lowest social expenditure among OECD countries, roughly 7.5% of GDP.

The Mexican economy has maintained macroeconomic stability, reducing inflation and interest rates to record lows. Despite this, significant gaps persist between the urban and the rural population, the northern and southern states, and the rich and the poor. Some of the unresolved issues include the upgrade of infrastructure, the modernization of the tax system and labor laws, and the reduction of income inequality. Tax revenues, 19.6 percent of GDP in 2013, were the lowest among the 34 OECD countries. The main problems Mexico faces are poverty rates and regional inequalities remaining high. The lack of formal employment, low access to financial services, and corruption has limited productivity growth. The medium-term growth prospects were also affected by a lower proportion of women in the workforce, and low investment since 2015.

Socioeconomic mobility in the United States refers to the upward or downward movement of Americans from one social class or economic level to another, through job changes, inheritance, marriage, connections, tax changes, innovation, illegal activities, hard work, lobbying, luck, health changes or other factors.

This mobility can be the change in socioeconomic status between parents and children ("inter-generational"); or over the course of a person's lifetime ("intra-generational"). Socioeconomic mobility typically refers to "relative mobility", the chance that an individual American's income or social status will rise or fall in comparison to other Americans, but can also refer to "absolute" mobility, based on changes in living standards in America.

World-systems theory (also known as world-systems analysis or the world-systems perspective) is a multidisciplinary approach to world history and social change which emphasizes the world-system (and not nation states) as the primary (but not exclusive) unit of social analysis. World-systems theorists argue that their theory explains the rise and fall of states, income inequality, social unrest, and imperialism.

The "world-system" refers to the inter-regional and transnational division of labor, which divides the world into core countries, semi-periphery countries, and periphery countries. Core countries have higher-skill, capital-intensive industries, and the rest of the world has low-skill, labor-intensive industries and extraction of raw materials. This constantly reinforces the dominance of the core countries. This structure is unified by the division of labour. It is a world-economy rooted in a capitalist economy. For a time, certain countries have become the world hegemon; during the last few centuries, as the world-system has extended geographically and intensified economically, this status has passed from the Netherlands, to the United Kingdom and (most recently) to the United States.
