Malthusianism is an ideology that claims that the exponential growth of the human population will lead to economic collapse. The idea comes from Thomas Robert Malthus who was hired by the British Royal Family to falsely claim that the causes of the French Revolution was due to population growth, rather than class conflict.
This ideology has become the basis of the degrowth movement and climate activists, who receive enormous funding from the ruling elites.
In contrast to Malthusianism, pro-growth Marxists (such as Deng Xiaoping) propose that humanity is not constrained in the same way as animals are when it comes to their population growth.[1] Lyndon LaRocuhe expresses this ability to increase the human population with technology as the "Potential Relative Population Density."
Fox Green of the Space Commune has made a documentary called Consumerism: Can we buy a better world? which offers a critique of degrowth and malhtusianism.[2]
