Has anyone heard of a psychologist named R.D. Laing?

Yes. Everyone that can use GOOGLE.

Ronald David Laing (7 October 1927 – 23 August 1989), usually cited as R. D. Laing, was a Scottish psychiatrist who wrote extensively on mental illness – in particular, the experience of psychosis. Laing's views on the causes and treatment of serious mental dysfunction, greatly influenced by existential philosophy, ran counter to the psychiatric orthodoxy of the day by taking the expressed feelings of the individual patient or client as valid descriptions of lived experience rather than simply as symptoms of some separate or underlying disorder. Laing was associated with the anti-psychiatry movement, although he rejected the label. Politically, he was regarded as a thinker of the New Left.

Laing was seen as an important figure in the anti-psychiatry movement, along with David Cooper, although he never denied the value of treating mental distress. He challenged the core values of a practice of psychiatry which he thought considered mental illness as a biological phenomenon without regard for social, intellectual and cultural dimensions.

He also challenged psychiatric diagnosis itself, arguing that diagnosis of a mental disorder contradicted accepted medical procedure: diagnosis was made on the basis of behavior or conduct, and examination and ancillary tests that traditionally precede the diagnosis of viable pathologies (like broken bones or pneumonia) occurred after the diagnosis of mental disorder (if at all). Hence, according to Laing, psychiatry was founded on a false epistemology: illness diagnosed by conduct, but treated biologically.

Laing maintained that schizophrenia was "a theory not a fact"; he believed the models of genetically inherited schizophrenia being promoted by biologically based psychiatry were not accepted by leading medical geneticists. He rejected the "medical model of mental illness"; according to Laing diagnosis of mental illness did not follow a traditional medical model; and this led him to question the use of medication such as antipsychotics by psychiatry. His attitude to recreational drugs was quite different; privately, he advocated an anarchy of experience.

He did not claim that US Capitalism is creating this current problem of mental illness. He died before all the firearm issues became so prevalent.

Anti-Oedipus: Capitalism and Schizophrenia (French: L'anti-Oedipe) is a 1972 book by the French philosopher Gilles Deleuze and the psychoanalyst Félix Guattari. It is the first volume of Capitalism and Schizophrenia, the second being A Thousand Plateaus (1980).

Deleuze and Guattari analyze the relationship of desire to reality and to capitalist society in particular; they address questions of human psychology, economics, society, and history. Anti-Oedipus is divided into four sections. In the first, Deleuze and Guattari outline a "materialist psychiatry" modeled on the unconscious in its relationship with society and its productive processes; in this section they introduce their concept of "desiring-production" (which inter-relates "desiring machines" and a "body without organs").

In the second section, Deleuze and Guattari offer a critique of Sigmund Freud's psychoanalysis that focuses on its theory of the Oedipus complex. In the third section, Deleuze and Guattari re-write Karl Marx's materialist account of the history of society's modes of production as a development through "primitive," "despotic," and "capitalist" societies and details their different organizations of production, "inscription" (which corresponds to Marx's "distribution" and "exchange"), and consumption. In the final section, they develop a critical practice that they call "schizoanalysis."

The authors draw on and criticize the ideas of many thinkers; in addition to Marx and Freud, these include Louis Althusser, Michel Foucault, Jacques Lacan, Wilhelm Reich, R. D. Laing, David Cooper, Carl Jung, Melanie Klein, Jean Oury, Georges Bataille, Karl Jaspers, Louis Hjelmslev, Charles Sanders Peirce, Gregory Bateson, Pierre Clastres, Claude Lévi-Strauss, Pierre Klossowski, Jean-François Lyotard, Jacques Monod, Lewis Mumford, Victor Turner, Karl August Wittfogel, Charles Fourier, Immanuel Kant, and Baruch Spinoza.
