But another question is, what people in Beijing supposed to do?
Think of that. To many, it's very clear that men in black will not be content even if given suffrage. Then they will want places in legislature, own foreign policy, armed forces, and ultimately sovereignty.
The popular sentiment that it's "poor HK kids" coming out at large out of desperation for their material situation can't hold water. Most of activists are children of very well off people, well educated, with a lot of life experience overseas, who had their future well being secured by their parents. No way they will be appeased with just a carrot.
The Party is well aware of that. There for long been a sentiment that Hongkong is a "trojan horse" the West gave to China, and the current crisis only reinforces this opinion among people in Beijing, and down to junior-mid-level cadres. There is no way the Party will back down.
This mess will take years to settle down in any scenario.
The General in Nigeria who overthrew the President in a Coup then handed power over to a new democratically elected President a year later.
Yes. Good, honest upstanding men (and women) will destroy their own position and power when it's the right thing to to.
The hard part is finding the Good and honest ones, and I suspect they are very few are far between in the Chinese leadership.
People on level municipalities, and provinces may show some rare signs of common sense from time to time, but them moment any of them (yes, even a provincial governor) will rise a hand, they will instantly be politically terminated.
And you have a system where tops are incapable of integrating any input for plainly neurological-biological reasons, and anybody with a shade of influence on them is super duper afraid of getting politically railroaded by both higher ups, and peers contending for promotion.
This is modern China for you.
