Many of the chinese investors made their money from being benefactors of government assets (mines etc) where as some were factory owners who through the opening of trade in china over the last 2 decades or so gave massive opportunities to these people to develop or produce products anything from clothing, building materials etc..
This kind of goes to my point about an unfair advantage, we all cant get rich off slave Labor ignoring safety costs etc, but yet we now have to compete for housing stock with those that can make a quid doing so.
You cant have a fair go society that comes at a cost and have others reap the benifits of the stability, safety and desirabilty that goes along with such a society only arriving there by means that are a complete antithesis for which our society is built.
And then competing against locals who do have to foot that cost for shelter.
