It becomes empirical evidence when the house price explosion occurred concurrently with the influx of Chinese in Sydney, Melbourne, Christchurch, Auckland, Toronto, London, Vancouver, and many other western cities. Property prices have been stagnant in Japan for decades after the bubble popped and have been equally increasing the moment Japan has seen an influx of Chinese workers and students. Hundreds of billions of dollars have left China over the past 2 decades...guess where this has been invested in?
The rise in condo prices were around the same time when chinese immigration exploded in Canada.
But I have no interest to argue over something that isn't statistically proven.
Like I said, it was just an observation/theory of mine. (Out of the blue.)
