You have to read these two little texts and say what you understand, if you agree or what you think.

1-The contrast between the contending economic theories of neoclassical, Keynesian, and Marxianeconomics is quite clear. It is important to note, that where neoclassical and Keynesian economic theories support capitalism as the most efficient economic framework, Marxian differs in this regard, taking "a critical position toward the the exploitation that it shows to be central to capitalist economies,and it seeks social change beyond capitalism in favor of anonexploitativeeconomy and society" (Wolff & Resnick, 2012, p. 134). With that being said, perhaps the most significant divergence between Keynesianand neoclassical economic theoriesis intheir views of government intervention during economic downturns.Where neoclassical theory holds that the market will correct itself, and explains imbalances in supply and demand as a cause of external factors, Keynesian theory, on the other hand says, "unemployed labor is the deep problem of capitalism; its solution lies in boosting effective demand via state action" (Wolff & Resnick, 2012, p. 108). In terms of state action, Keynesian theory provided a breakthrough answer to the recession in 2008, when President BarackObamalaunched his $800 billion stimulus program in 2009 aimed at boosting growth through tax breaks for individuals and firms, government contracts, grants, loans, unemployment benefits, food stamps, Medicaid, etc. (Cassidy, 2012). Thus, Obama'sstimulus program represented a far reaching state policy plan with Keynesian theory at its very core.

2- In economics, Capitalism has changed drastically with different variations of those mentioned pillars (Wolff and Resnick, 2012). The swift from one form of Capitalism to another happens slowly and gradually to adapt to changes in the contextual society and eliminate weaknesses identified. The original Capitalism of Adam Smith, in theory, highlights private property, competition, and a market mechanism with the concept of "the invisible hand" (Wolff and Resnick, 2012). The role of government in Smith's theory is minimal. However, after years of development, the government's importance has improved and been entrusted with more crucial decisions to monitor the economy (Lane, 2019)
