Studies on the Zapatistas show they have better access to services than in the pro-government Mexican communities, and deal with less hunger, poverty and violence. They have lived this way since 1994.
Rojava has been using a libertarian socialist model called democratic confederalism, inspired by anarchist/libertarian thinker Murray Bookchin. They’ve lived this way since about 2012 I think.
Cuba has a higher life expectancy and literacy rate than the U.S. and is considered the most sustainably developed country in the entire world, despite having a Marxist-Leninist form of government.
Almost all reductions in global poverty can be attributed to China (East Asia) and the left-wing governments in Latin America. I would say that is a significant success.
Vietnam has captured the attention of the economic elites because their economy is thriving, and they have a market socialist form of government under the Communist Party.
Left-wing movements tend to change things for working people, whereas capitalist movements do things for businesses. Too often, the U.S. sabotages left-wing governments or movements to support right-wing authoritarianism. President Allende, the first democratically elected Marxist president in the world, in Chile had very helpful programs for the people, like providing free milk to children, land redistribution, increasing wages, but the U.S. supported a coup that overthrew him and Pinochet, his installed replacement, murdered socialists.
