Don't demonise the mainlanders for a property orgy of our own making.
HKG locals are also calling mainland shoppers "locusts" and "rats", blaming them for increasing prices and short supplies.
Who exactly is putting up the rents?
Who has dropped any resemblance of border control for mainland visitors?
I've had the personal experience of meeting the asking price of a property in HKG in an offer, only to have it rejected BY THE VENDOR - with a disproportionate increase - "because I didn't argue about the price".
This has the makings of another "Kristallnacht". Be very, very careful.
