Hi Jakub, having done comparative philosophy for some time, I think the issue of human rights can't easily be solved with changes in economic structure. Nor would protest be effective - as you've mentioned the Tiananmen case.
The heart of the issue, I think is far deeper. It has to do with the Chinese culture in general.
For starters, many East Asian societies do not possess the historical or cultural material to properly construct 'rights', as understood in the West. As such, how people in these cultures understand the individual is vastly different from the West.
Sure, we could import these values directly, and some might even adopt it. But I like to use the analogy of learning a language when we're adults. It'll never be the same way as learning a language when we're kids. We will use what we already understand about the world to learn a foreign language. The same goes with foreign concepts such as 'rights' and 'freedom'.
Perhaps an economic disaster may perpetuate a radical shift in the Chinese culture. It could also affect the course of its history. But unless the culture can properly construct 'rights' with it's own hermeneutics, it'll be difficult for them to appreciate it.
I discuss part of this in one of my articles: https://theapeiron.co.uk/dear-democracy-we-need-more-than-rights-3e6056f0f16a
I'd like to know what you think!
