It is a very brief summary of many concepts in economics from the Austrian school libertarian perspective. It discusses and refutes many fallacies and misconceptions from the monetary school, marxist school and Keynesian school. Very interesting approach to the concepts of Profit/Loss, minimum wage, antitrust laws, federal reserve, etc... The most interesting chapter is the assassination of the marxist labour theory through rational and well given examples. Highly recommended read... However, in very few sections, stronger and more convincing examples could have been used mainly when he discusses monopoly.
