A poll conducted for Reuters by an institute whose ex-CEO has historically expressed anti-Beijing and HK pro-succession views and has since moved to UK.[1] Yea, no bias there.

Even in that survey, you can clearly see that the locals did not want all the things the protestors/western media wanted.
Nevertheless, only 17% expressed support for seeking independence from China, and 20% were opposed to "the current path of one country, two systems" - the arrangement under which Hong Kong is governed by Beijing.
Many protesters say Beijing has used its authority under the system to gradually undermine certain freedoms - such as an independent judiciary and freedom of speech - that are supposed to be guaranteed at least until 2047 under the arrangement.
The results of the survey, involving 1,021 people and conducted from Dec. 17-20, also showed a large plurality of respondents mainly blamed the Hong Kong government for the crisis, the worst civil unrest to hit the city in decades, rather than the central government in Beijing.
This paper directly contradicts your claim it was mainly due to housing [4].
Summarize it? Having lived in Hong Kong and talked to many locals, had local friends, talked to young HKers, no one could convince me that housing wasn't the biggest reason for the pent up frustration that ultimately led to the protests.
