instruction: Give me a bulleted list of 3 books Thomas Sowell has written and what they are about.
context: Until the spring of 1972, Sowell was a registered Democrat, after which he then left the Democratic Party and resolved not to associate with any political party again, stating "I was so disgusted with both candidates that I didn't vote at all." Though he is often described as a black conservative, Sowell said, "I prefer not to have labels, but I suspect that 'libertarian' would suit me better than many others, although I disagree with the libertarian movement on a number of things." He has been described as one of the most prominent advocates of contemporary classical liberalism along with Friedrich Hayek and Larry Arnhart. Sowell primarily writes on economic subjects, generally advocating a free market approach to capitalism. Sowell opposes the Federal Reserve, arguing that it has been unsuccessful in preventing economic depressions and limiting inflation. Sowell described his study of Karl Marx in his autobiography; as a former Marxist who early in his career became disillusioned with it, he emphatically opposes Marxism, providing a critique in his book Marxism: Philosophy and Economics (1985).
  
  Sowell has also written a trilogy of books on ideologies and political positions, including A Conflict of Visions, in which he speaks on the origins of political strife; The Vision of the Anointed, in which he compares the conservative/libertarian and liberal/progressive worldviews; and The Quest for Cosmic Justice, in which, as in many of his other writings, he outlines his thesis of the need felt by intellectuals, politicians, and leaders to fix and perfect the world in utopian and ultimately, he posits, disastrous fashions. Separate from the trilogy, but also in discussion of the subject, he wrote Intellectuals and Society, building on his earlier work, in which he discusses what he argues to be the blind hubris and follies of intellectuals in a variety of areas.
  
  His book Knowledge and Decisions, a winner of the 1980 Law and Economics Center Prize, was heralded as a "landmark work," selected for this prize "because of its cogent contribution to our understanding of the differences between the market process and the process of government." In announcing the award, the centre acclaimed Sowell, whose "contribution to our understanding of the process of regulation alone would make the book important, but in reemphasizing the diversity and efficiency that the market makes possible,  work goes deeper and becomes even more significant." Friedrich Hayek wrote: "In a wholly original manner [Sowell] succeeds in translating abstract and theoretical argument into highly concrete and realistic discussion of the central problems of contemporary economic policy."
  
  Sowell opposes the imposition of minimum wages by governments, arguing in his book Basic Economics that "Unfortunately, the real minimum wage is always zero, regardless of the laws, and that is the wage that many workers receive in the wake of the creation or escalation of a government-mandated minimum wage, because they either lose their jobs or fail to find jobs when they enter the labor force." He goes further to argue that minimum wages disproportionately affect "members of racial or ethnic minority groups" that have been discriminated against. He asserts that "Before federal minimum wage laws were instituted in the 1930s, the black unemployment rate was slightly lower than the white unemployment rate in 1930. But then followed the Davis-Bacon Act of 1931, the National Industrial Recovery Act (NIRA) of 1933 and the Fair Labor Standards Act (FLSA) of 1938 – all of which imposed government-mandated minimum wages, either on a particular sector or more broadly... By 1954, black unemployment rates were double those of whites and have continued to be at that level or higher. Those particularly hard hit by the resulting unemployment have been black teenage males."
  
  Sowell also favors decriminalization of all drugs. He opposes gun control laws, arguing, "On net balance, they do not save lives, but cost lives."[
