I'll get to those declarations in a little bit. Instead let's talk about their quality of life. They have a higher life expectancy, virtually no homelessness, healthcare is a right, people are more free to persue passions like healthcare, science, and mathematics, among several other similarities. Cuba in particular has a longer life expectancy, higher literacy rates, better healthcare outcomes, and lower infant mortality when compared to the US. The minimum wage in Cuba is equivalent to USD$17.50/hr, and the median wage is USD$33/hr. Cuba and Vietnam outperform comparable countries in most socioeconomic indicators. That is what I mean by proletarian democracy, even if I'd call the economies in those countries "state capitalism". There's a youtuber from Vietnam called Luna oi! that discusses what it's actually like to live in Vietnam as a citizen, she provides valuable insight into the political life of citizens.
