File:DiagFuncMacroSyst.pdf An economic system is the combination of the various agencies, entities (or even sectors as described by some authors) that provide the economic structure that defines the social community. These agencies are joined by lines of trade and exchange along which goods, money etc. are continuously flowing. An example of such a system for a closed economy is shown in the flow-diagram. The economics system involves production, allocation of economic inputs, distribution of economic outputs, Landlords and land availability, households (earnings and expenditure consumption of goods and services in an economy), Capitalists, Banks (finance institutions) and Government. It is a set of institutions and their various social relations.

Alternatively, it is the set of principles by which problems of economics are addressed, such as the economic problem of scarcity through allocation of finite productive resources. An economic system is composed of people, institutions, rules, and relationships. For example, the convention of property, the institution of government, or the employee-employer relationship. Examples of contemporary economic systems include capitalist systems, socialist systems, and mixed economies. Today the world largely operates under a global economic system based on the capitalist mode of production.

George Denis Patrick Carlin (May 12, 1937 – June 22, 2008) was an American stand-up comedian, social critic, satirist, actor and writer/author, who won five Grammy Awards for his comedy albums.

Carlin was noted for his black humor as well as his thoughts on politics, the English language, psychology, religion, and various taboo subjects. Carlin and his "Seven Dirty Words" comedy routine were central to the 1978 U.S. Supreme Court case F.C.C. v. Pacifica Foundation, in which a narrow 5–4 decision by the justices affirmed the government's power to regulate indecent material on the public airwaves.

The first of his fourteen stand-up comedy specials for HBO was filmed in 1977. In 1988, the 1990s and 2000s, Carlin's routines focused on socio-cultural criticism of modern American society. He often commented on contemporary political issues in the United States and satirized the excesses of American culture. His final HBO special, It's Bad for Ya, was filmed less than four months before his death.

Karl Heinrich Marx (5 May 1818 – 14 March 1883) was a German philosopher, economist, sociologist, historian, journalist, and revolutionary socialist. His ideas played a significant role in the development of social science and the socialist political movement. He published various books during his lifetime, with the most notable being The Communist Manifesto (1848) and Capital (1867–1894); some of his works were co-written with his friend and fellow German revolutionary socialist, Friedrich Engels.

Born into a wealthy middle class family in Trier, formerly in Prussian Rhineland now called Rhineland-Palatinate, Marx studied at both the University of Bonn and the University of Berlin, where he became interested in the philosophical ideas of the Young Hegelians. In 1836, he became engaged to Jenny von Westphalen, marrying her in 1843. After his studies, he wrote for a radical newspaper in Cologne, and began to work out his theory of dialectical materialism. Moving to Paris in 1843, he began writing for other radical newspapers. He met Engels in Paris, and the two men worked together on a series of books. Exiled to Brussels, he became a leading figure of the Communist League, before moving back to Cologne, where he founded his own newspaper. In 1849 he was exiled again and moved to London together with his wife and children. In London, where the family was reduced to poverty, Marx continued writing and formulating his theories about the nature of society and how he believed it could be improved, and also campaigned for socialism—he became a significant figure in the International Workingmen's Association.

Joseph Alois Schumpeter (8 February 1883 – 8 January 1950) was an Austrian-Hungarian-American economist and political scientist. He popularized the term "creative destruction" in economics.

Born in Třešť, Habsburg Moravia (now Czech Republic, then part of Austria-Hungary) in 1883 to Catholic ethnic German parents. His father owned a factory, but he died when Joseph was only four years old. In 1893, Joseph and his mother moved to Vienna.

Schumpeter began his career studying law at the University of Vienna under the Austrian capital theorist Eugen von Böhm-Bawerk, taking his PhD in 1906. In 1909, after some study trips, he became a professor of economics and government at the University of Czernowitz. In 1911 he joined the University of Graz, where he remained until World War I. In 1919, he served briefly as the Austrian Minister of Finance, with some success, and in 1920–1924, as president of the private Biedermann Bank. That bank, along with a great part of that regional economy, collapsed in 1924 leaving Schumpeter bankrupt.

Israr Ahmed (Urdu: اسرار احمد; April 26, 1932 – April 14, 2010) was a Pakistani Islamic theologian followed particularly in South Asia and also among the South Asian diaspora in the Middle East, Western Europe, and North America. Born in Hissar, (today's Haryana) in India, the second son of a government servant, he is the founder of the Tanzeem-e-islami, an off-shoot of the Jamaat-e-Islami.He has spent more than 50 years preaching Quraan.He hosted a daily show on Peace TV, a 24 hours Islamic channel broadcast internationally, and until recently^[when?] on ARY Qtv.

Ahmad was born on April 26, 1932 in Hisar (a district of East Punjab, now a part of Haryana) in India, the second son of a government servant. He graduated from King Edward Medical College (Lahore) in 1954 and later received his Master's degree in Islamic Studies from the University of Karachi in 1965. He came under the influence of 'Abul Ala Maududi' as a young student, worked briefly for Muslim Student's Federation in the Independence Movement and, following the creation of Pakistan in 1947, for the Islami Jamiat-e-Talaba and then for the Jamaat-e-Islami. Ahmad resigned from the Jama`at in April 1957 because of its involvement in the electoral politics, which he believed was irreconcilable with the revolutionary methodology adopted by the Jama'at in the pre-1947 period.
