Scott Alexander examines the justification for billionaire wealth, introducing the concept of replaceability to challenge the standard neoliberal defense. Longer summary

Scott Alexander explores the concept of billionaire wealth and its justification, starting with the neoliberal defense that entrepreneurs create value and deserve a portion of it. He then introduces a counterargument based on replaceability: if an entrepreneur hadn't existed, someone else would likely have filled that economic niche eventually.
