if people did the right thing, like if they have the virus - don't go spread it around knowing or unknowling (ie not getting tested) then everything you say is great, but people don't, just look how many in the US that don't 200,000 a day because someone won't wash the hands (abbreviation for all the things they should do),
and yes why should the whole be held ransom to the few.. because the few are spread a killer virus that also can criple for years to come - not all but some.
i know a family of 5, there kids, trying to do the right thing....they see the numbers in the US, very learned people, the mother told me other day their main concern is the possilbe spread via the school. ...many case throughout of schools being shut down.
we should be thank ful being in Australia.. but we won't have had the little bit of the virus causing such big problems if again everyone did the right thing.
be safe everyone
