Fair point. My comment was only in response to GP's sentence about quelling protests on the Mainland. I doubt any such tactic would be effective in a highly educated and already distrustful population like that of HK.
Yeah, to that I agree. I have a colleague from China and in her experience, moving from her smaller city (population 300 000) to Shanghai was a big eye opener for her. She was exposed to more educated people and more sources of information outside CCP control.
The tactics you describe to quell protests would definitely work in her hometown and 90% of all other population centers in China. The other 10% are doing great and don’t feel like protesting the smaller issues.
