Illegal immigration is the migration into a country/state in violation of the immigration laws and sovereignty of that country/state. Illegal immigration raises many political, economic and social issues and has become a source of major controversy in developed countries and the more successful developing countries.

In 2010, the International Organization for Migration (IOM) estimated that 25.5 to 32.1 million people (or 10%–15%) of the world's total 214 million international immigrants are illegal immigrants, though the IOM notes that it is difficult to make accurate estimates.

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.

Michelle Fields is a political journalist. Upon graduating from Pepperdine University in 2011, she gained attention after having a heated confrontation with actor Matt Damon over teacher tenure reform. After the Damon altercation, Fields was hired as a reporter by Tucker Carlson at The Daily Caller.

Fields was born in Los Angeles and grew up in the San Fernando Valley. She is Honduran American and is the daughter of television and film writer Greg Fields. She credits her older brother, who encouraged her to read Robert Nozick, for helping her realize she is "pro-liberty."

She studied political science at Pepperdine University and served as the president of the Pepperdine chapter of Students For Liberty.

Fields covered the Occupy Movement in both New York City and Washington, DC. Her sometimes critical coverage of Occupy DC garnered harassment from protesters when a demonstration turned violent.

Fields is known for filming and editing her videos in citizen journalism style. She credits the internet for launching her career and believes that the popularity of her videos is due to her citizen journalism style of reporting. In an interview with C-SPAN in 2011 she said that the use of the internet has empowered people so much that now "one voice can be just as powerful as the New York Times."
