As I mentioned in my earlier posts, these protests are manifestation of inherent economic inequality in Hong Kong society.
The youth in Hong Kong cannot afford a house. The whole economy is standing on a giant real estate bubble under the control of 14 rich billionaires.
This protests can already be foreseen when property was becoming unaffordable without an increase in salary, it was just a matter of time.
Britain is as much to blame for this situation, they never had intention to grant autonomy to Hong Kong and didn't do it for 150 years, they were very clever, as they did in every colony, to let the subsequent administration take the blame in this case Chinese which indeed granted more autonomy than British to Hong Kong.
Britain can cry crocodile tears now as much as they like trying to align with protestors. But they are the one to blame. Hopefully they can correct the mistake by granting full citizenship to Hong Kong permanent residents who wants it, otherwise whatever they say is a farce. Same goes for USA, if they want solidarity with Hong Kong protestors grant them unconditional asylum or permanent residence, rest all talks are worthless.
