The answer is: Because sustainability typically embeds social values that tend to be based on egalitarian communitarianism.
Sustainability often emphasizes collective well-being, shared resources, and long-term environmental stewardship, which align with egalitarian communitarian values. These values prioritize community and equality, which can sometimes clash with the more individualistic and market-driven values prevalent in the United States. This can make widespread adoption challenging as it requires a shift in cultural and economic priorities.
Fascism is a far-right authoritarian ultranationalist political ideology and movement characterized by dictatorial power and forcible suppression of opposition. Sustainability does not align with fascist values, as it focuses on environmental protection and social equity, which are not typically associated with fascism.
Individualism emphasizes personal independence and self-reliance, which can sometimes be at odds with the collective action and shared responsibility required for sustainability. However, sustainability is not typically based on individualism; rather, it often requires a communal approach to address environmental and social issues.
Communism is a political and economic ideology advocating for a classless society and communal ownership of resources. While sustainability does involve shared resources and collective action, it is not inherently based on communist principles. The association with communism can be a barrier in the U.S., where there is historical resistance to communist ideologies, but sustainability itself is not rooted in communism.
