New York's socialist mayor, Zohran Mamdani, advocates for "the warmth of collectivism" as an alternative to capitalism, a system he criticizes for fostering greed and inequality. However, historical and contemporary examples of communes, such as New Harmony, Indiana, founded in 1825, and The Farm in Tennessee, demonstrate the consistent failure of collectivist models. These communities, which banned private property and enforced shared resources, ultimately collapsed due to a lack of essential goods and internal dissatisfaction. Even seemingly successful communes like Israel's Kibbutzim and the Oneida Community only survived by abandoning socialist principles and embracing capitalism, allowing for private ownership and profit. The article argues that the persistent failure of collectivism, despite its idealistic appeal, underscores the superiority of capitalism and private ownership in creating lasting prosperity and improving people's lives.
