Nouveau riche in the context of "Conspicuous consumption"

Upper class in modern societies is the social class composed of people who hold the highest social status. Usually, these are the wealthiest members of class society, and wield the greatest political power. According to this view, the upper class is generally distinguished by immense wealth which is passed on from generation to generation. Prior to the 20th century, the emphasis was on aristocracy, which emphasized generations of inherited noble status, not just recent wealth.

Because the upper classes of a society may no longer rule the society in which they are living, they are often referred to as the old upper classes, and they are often culturally distinct from the newly rich middle classes that tend to dominate public life in modern social democracies. According to the latter view held by the traditional upper classes, no amount of individual wealth or fame would make a person from an undistinguished background into a member of the upper class as one must be born into a family of that class and raised in a particular manner to understand and share upper class values, traditions, and cultural norms. The term is often used in conjunction with terms like upper-middle class, middle class, and working class as part of a model of social stratification.

The Kazoku (華族, "Magnificent/Exalted lineage"; IPA: [ka̠zo̞kɯ̟]) was the hereditary peerage of the Empire of Japan, which existed between 1869 and 1947. It was formed by merging the feudal lords (daimyō) and court nobles (kuge) into one system modelled after the British peerage. Distinguished military officers, politicians, and scholars were occasionally ennobled as (新華族, shin kazoku, 'the newly ennobled'), until the country's defeat in the Second World War in 1945. The system was abolished with the 1947 constitution, which prohibited any form of aristocracy under it, but kazoku descendants still form the core of the traditional upper class in the country's society, distinct from the nouveau riche.

Kazoku (華族) should not be confused with kazoku (家族), which is pronounced the same in Japanese, but written with different characters, meaning "immediate family" (as in the film Kazoku above).

The Grand Tour was the principally 17th- to early 19th-century custom of a traditional trip through Europe, with Italy as a key destination, undertaken by upper-class young European men of sufficient means and rank (typically accompanied by a tutor or family member) when they had come of age (about 21 years old). The custom—which flourished from about 1660 until the advent of large-scale rail transport in the 1840s and was associated with a standard itinerary—served as an educational rite of passage. Though it was primarily associated with the British nobility and wealthy landed gentry, similar trips were made by wealthy young men of other Protestant Northern European nations, and, from the second half of the 18th century, by some North and South Americans.

By the mid-18th century, the Grand Tour had become a regular feature of aristocratic education in Central Europe as well, although it was restricted to the higher nobility. The tradition declined in Europe as enthusiasm for classical culture waned, and with the advent of accessible rail and steamship travel—an era in which Thomas Cook made the "Cook's Tour" of early mass tourism a byword starting in the 1870s. However, with the rise of industrialization in the United States in the 19th century, American Gilded Age nouveau riche adopted the Grand Tour for both sexes and among those of more advanced years as a means of gaining both exposure and association with the sophistication of Europe. Even those of lesser means sought to mimic the pilgrimage, as satirized in Mark Twain's popular travel book The Innocents Abroad in 1869.

The German nobility (deutscher Adel) and royalty were status groups of the medieval society in Central Europe, which enjoyed certain privileges relative to other people under the laws and customs in the German-speaking area, until the beginning of the 20th century. Historically, German entities that recognized or conferred nobility included the Holy Roman Empire (962–1806), the German Confederation (1814–1866), and the German Empire (1871–1918). Chancellor Otto von Bismarck in the German Empire had a policy of expanding his political base by ennobling nouveau riche industrialists and businessmen who had no noble ancestors. The nobility flourished during the dramatic industrialization and urbanization of Germany after 1850. Landowners modernized their estates, and oriented their business to an international market. Many younger sons were positioned in the rapidly growing national and regional civil service bureaucracies, as well as in the officer corps of the military. They acquired not only the technical skills but also the necessary education in high prestige German universities that facilitated their success. Many became political leaders of new reform organizations such as agrarian leagues, and pressure groups. The Roman Catholic nobility played a major role in forming the new Centre Party in resistance to Bismarck's anti-Catholic Kulturkampf, while Protestant nobles were similarly active in the Conservative Party.

In August 1919, at the beginning of the Weimar Republic (1918–1933), Germany's new constitution officially abolished royalty and nobility, and the respective legal privileges and immunities appertaining to an individual, a family or any heirs.

The New Economic Policy (NEP) (Russian: новая экономическая политика (НЭП), romanized: novaya ekonomicheskaya politika) was an economic policy of the Soviet Union proposed by Lenin in 1921 as a temporary expedient. Lenin characterized the NEP in 1922 as an economic system that would include "a free market and capitalism, both subject to state control", while socialized state enterprises would operate on "a profit basis". Nouveau riche people who took an advantage of the NEP were called NEPmen (нэпманы).

The NEP represented an early form of market socialism to foster economic growth for the country, which had suffered severely since World War I and the Russian Civil War. The Soviet authorities partially revoked the complete nationalization of industry (established during the period of war communism of 1918 to 1921) and introduced a mixed economy which allowed private individuals to own small and medium-sized enterprises, while the state continued to control large industries, banks and foreign trade. The Bolshevik government adopted the NEP in the course of the 10th Congress of the All-Russian Communist Party (March 1921). The decree on 21 March 1921: "On the Replacement of Prodrazvyorstka by Prodnalog" abolished forced grain-requisition (prodrazvyorstka) and introduced a tax on farmers, payable in the form of raw agricultural product (prodnalog). Further decrees refined the policy. Other policies included monetary reform (1922–1924) and the attraction of foreign capital.
