That's not really the point is it? 
What posters like you encourage is an anti-Chinese, anti-immigration bias by suggesting that the "rest of us" point fingers at such groups and blame them for the housing woes. But it's not them who's to blame but the system that allows it to happen. They are just the evidence of its happening, not the cause.
Do you blame them for being here? Outside of the housing issue (where they are exercising their perfectly legal rights), are you harmed or affected by them in any way? No, but the tone of posts like yours raises race as an issue, which can do nothing but inflame feelings.
Go after governments. They are the ones who must solve the issue, not the people who have found a way to benefit from government policies under current rules.
