Do you have any source on the PRC killing or imprisoning anyone who complains about it? Moreover, what do you think about 95%+ Chinese citizens supporting the CPC? If we ask Harvard themselves about the results of their study, they say "We find that first, since the start of the survey in 2003, Chinese citizen satisfaction with government has increased virtually across the board. From the impact of broad national policies to the conduct of local town officials, Chinese citizens rate the government as more capable and effective than ever before. Interestingly, more marginalized groups in poorer, inland regions are actually comparatively more likely to report increases in satisfaction. Second, the attitudes of Chinese citizens appear to respond (both positively and negatively) to real changes in their material well-being, which suggests that support could be undermined by the twin challenges of declining economic growth and a deteriorating natural environment." This directly goes against claims of "social credit" preventing this, moreover the "Orwellian Social Credit System" hinted at doesn't even exist, at least not in the manner most think it does. Even more overtly, they state "Although state censorship and propaganda are widespread, our survey reveals that citizen perceptions of governmental performance respond most to real, measurable changes in individuals’ material well-being."
