Conscription in the United States has been employed several times, usually during war but also during the nominal peace of the Cold War. The United States discontinued the draft in 1973, moving to an all-volunteer military force, thus there is no mandatory conscription.

However, the Selective Service System remains in place as a contingency plan; men between the ages of 18 and 25 are required to register so that a draft can be readily resumed if needed. In current conditions conscription is considered unlikely by most political and military experts.

In colonial times, the Thirteen Colonies used a militia system for defense. Colonial militia laws—and after independence those of the United States and the various states—required able-bodied males to enroll in the militia, to undergo a minimum of military training, and to serve for limited periods of time in war or emergency. This earliest form of conscription involved selective drafts of militiamen for service in particular campaigns. Following this system in its essentials, the Continental Congress in 1778 recommended that the states draft men from their militias for one year's service in the Continental army; this first national conscription was irregularly applied and failed to fill the Continental ranks.

Peter "Pete" Seeger (born May 3, 1919) is an American folk singer and an iconic figure in the mid-20th-century American folk music revival. A fixture on nationwide radio in the 1940s, he also had a string of hit records during the early 1950s as a member of The Weavers, most notably their recording of Lead Belly's "Goodnight, Irene", which topped the charts for 13 weeks in 1950. Members of The Weavers were blacklisted during the McCarthy Era. In the 1960s, he re-emerged on the public scene as a prominent singer of protest music in support of international disarmament, civil rights, and environmental causes.

As a song writer, he is best known as the author or co-author of "Where Have All the Flowers Gone?", "If I Had a Hammer (The Hammer Song)", (composed with Lee Hays of The Weavers), and "Turn, Turn, Turn!", which have been recorded by many artists both in and outside the folk revival movement and are still sung throughout the world. "Flowers" was a hit recording for The Kingston Trio (1962); Marlene Dietrich, who recorded it in English, German and French (1962); and Johnny Rivers (1965). "If I Had a Hammer" was a hit for Peter, Paul & Mary (1962) and Trini Lopez (1963), while The Byrds popularized "Turn, Turn, Turn!" in the mid-1960s, as did Judy Collins in 1964, and The Seekers in 1966. Seeger was one of the folksingers most responsible for popularizing the spiritual "We Shall Overcome" (also recorded by Joan Baez and many other singer-activists) that became the acknowledged anthem of the 1960s American Civil Rights Movement, soon after folk singer and activist Guy Carawan introduced it at the founding meeting of the Student Nonviolent Coordinating Committee (SNCC) in 1960. In the PBS "American Masters" episode Pete Seeger: The Power of Song, Seeger states it was he who changed the lyric from the traditional "We will overcome" to the more singable "We shall overcome".

Milton Friedman (July 31, 1912 – November 16, 2006) was an American economist, statistician, and author who taught at the University of Chicago for more than three decades. He was a recipient of the Nobel Memorial Prize in Economic Sciences, and is known for his research on consumption analysis, monetary history and theory, and the complexity of stabilization policy. As a leader of the Chicago school of economics, he influenced the research agenda of the economics profession. A survey of economists ranked Friedman as the second most popular economist of the twentieth century behind John Maynard Keynes, and The Economist described him as "the most influential economist of the second half of the 20th century…possibly of all of it."

Friedman's challenges to what he later called "naive Keynesian" (as opposed to New Keynesian) theory began with his 1950s reinterpretation of the consumption function, and he became the main advocate opposing activist Keynesian government policies. In the late 1960s he described his own approach (along with all of mainstream economics) as using "Keynesian language and apparatus" yet rejecting its "initial" conclusions. During the 1960s he promoted an alternative macroeconomic policy known as "monetarism". He theorized there existed a "natural" rate of unemployment, and argued that governments could increase employment above this rate (e.g., by increasing aggregate demand) only at the risk of causing inflation to accelerate. He argued that the Phillips curve was not stable and predicted what would come to be known as stagflation. Friedman argued that, given the existence of the Federal Reserve, a constant small expansion of the money supply was the only wise policy.

Philip David Ochs ( /ˈoʊks/; December 19, 1940 – April 9, 1976) was an American protest singer (or, as he preferred, a topical singer) and songwriter who was known for his sharp wit, sardonic humor, earnest humanism, political activism, insightful and alliterative lyrics, and distinctive voice. He wrote hundreds of songs in the 1960s and released eight albums in his lifetime.

Ochs performed at many political events, including anti-Vietnam War and civil rights rallies, student events, and organized labor events over the course of his career, in addition to many concert appearances at such venues as New York City's Town Hall and Carnegie Hall. Politically, Ochs described himself as a "left social democrat" who became an "early revolutionary" after the protests at the 1968 Democratic National Convention in Chicago led to a police riot, which had a profound effect on his state of mind.

After years of prolific writing in the 1960s, Ochs's mental stability declined in the 1970s. He eventually succumbed to a number of problems including bipolar disorder and alcoholism, and took his own life in 1976.
