Let's assume the CCP wants to eradicate slavery, but the people won't allow them to do that. Have you got evidence to support that assumption?
Since an assumption is any idea one accepts as accurate without knowing it is true, no, sir, I do not have evidence to support my claim. I cannot and do not ascribe intent concerning the CCP and its approach to domestic chattel slavery. It is a supposition based on the CCP's overall approach to the well-being of its citizenry, which is one of the world's finest. As mentioned, China's average life expectancy in 1949 was 36 years, which is currently 78.08 years.
According to the Pew Research Center, the percentage of China's workers in its middle-income strata increased from 3.1% in 2000 to slightly more than 50% by 2018. By the end of the 2020s, an additional 80 million workers will accompany them. By contrast, the U.S.'s "middle class" fell from 61% of its population in 1971 to roughly 50% today.
Therefore, it only makes sense that a government that has drastically increased average life expectancy, literacy, and education levels while drastically decreasing infant mortality, neonatal death rates, and other social ills would also strive to eliminate chattel slavery. Of course, it is also the case that some aspects of the CCP are actively subjecting Uyghurs in the Xinjiang region to chattel slavery. However, discrimination against Chinese Uyghur Muslims has been a cultural pathology for hundreds of years rather than a specific manifestation of the CCP.
Furthermore, the U.S. and British-led imperialist hypocrisy surrounding the issue of the oppression of Uyghurs is glaring. Among other concerns, the U.S., which has murdered millions of Muslims in the Middle East and Central Asia throughout the past twenty years, has no wiggle room to condemn the CCP concerning anything, let alone the subjugation of Muslims.
