While the violence (from both sides!) was absolutely wrong and must be stopped - those HK real estate billionaires ignore the fact that they are the real problem in Hong Kong, not lack of democracy, not China, and not the extradition bill. Hong Kong has high salaries and poor -very poor- quality of living as the real estates are so small, so uncomfortable, so expensive and mainly: monopolized. That's the real problem in Hong Kong, not the desire of the protesters to replicate the Arab spring catastrophe.
