It's worth responding to your edit in a separate comment.

First, China. That data shows 45% living under $10 a day, and has no data provided on the "poverty rate" column. Not only are you misreporting by 11%, but you are conveniently reporting the wrong data. Essentially, you reported the wrong quantity for the wrong quality. Furthermore, this data is half a decade old, when we know 3 years ago China completed a mass poverty aleviation campaign and over the course of around a decade uplifted 800 million people out of poverty.

Furthermore, 10 dollars gets you far more in different parts of China than the wealthier coastal cities, who were the first to be developed more thoroughly. Given that a century ago China was among the poorest countries in the world, its progress has been astounding overall, and in the more rural inland areas have been a major focus in the last decade. Unlike more developed countries, China is still a developing country, and as such despite its rapid improvement has a long way to go before every area is like one of the more developed tier 1 cities.

Secondly, the USSR. Not only is this article from a Private Christian College, it does't contradict that, again, wealth disparity shrank to one of the lowest in the world while maintaining some of the highest rates of economic growth in the world, free, high quality education and healthcare were provided, literacy rates more than tripled to the highest in the world, science, technology, culture, and even sports flourished. Life expectancy doubled, and despite having much of their housing destroyed by the Nazi invasion in WWII, they quickly built the now stereotyped "soviet bloc" housing to house as many people as possible.

All the article really seems to say, therefore, is that society wasn't perfect, which nobody here has said. It does not make the case that the Socialist system was worse than the semi-feudalism of before or the Capitalism it is today, rather, it just said some degree of corruption existed but in a way that was far less than it was before or after Socialism.

The fact that you are either intentionally or unintentionally reporting wrong numbers for wrong metrics that are already outdated as some "gotcha" for countries that began as some of the poorest on the planet, and use the fact that the aren't like the Nordic Countries, that have spend centuries pillaging and looting the Global South and had centuries longer to develop, is dishonest and ill-informed. I suggest reading Super Imperialism by Hudson if you want to take a modern (2021 is the latest revision) look at the way the Global North, and specifically the US, rob and loot the world.

You won't get it if you're taking the old bloke and his words at face value.

The meme value comes from the context, being a scene from LOTR.
