When I say 'we', I mean 'you' as I'm no longer there... you know what I mean!
Some people in HK seem to have a delusion that if we all stay home for 2 weeks then we can go back to how life was before the virus. It’s not going to happen. Not least because lots of people still have to work every day. Borders are closed to most of the world now but our friends up North aren’t going to stay away from HK indefinitely.
As to tests in HK being very low, your theory again doesn't make that much sense because they compare well with most countries and arrivals in HK have been only a few hundreds a day for a while now. If there was significant transmission in the community, we would see some more hospital admissions particularly in light of the fact that we are far from being in hard lockdown. Your number of asymptomatic carriers is taken completely out of thin air as this is not known. Sound logic says that if there were large numbers of asymptomatic carriers, some of those would eventually translate into hospital admissions or visits and positive tests. The idea that thousands of infected people roam around with nothing happening makes no sense.
As to the statement that Lam and her cronies are blaming transmission on foreigners coming to HK, that is even more ludicrous since the only ones allowed to come back to HK are HK residents and most of those returning are not westerners. A large number of these returnees were students who are not europeans or americans.
The vision you propose is one viewed through your eyes and definitely not one that I share and not based on too many solid facts.
