It's not that the government's response in disproportionate, its just that they screwed up at the start of the pandemic. Many "developing" countries like Vietnam and Cuba obliterated the virus and haven't gone into lockdown since iirc.
Vietnam is in harsh lockdown right now. Cuba has 10,000 cases a day. No one has managed to consistently demolish this but China, and our state governments have done far better than anyone but China with a far more liberal and rights-respecting position. You'll always have the international border issue, and aside from dedicated quarantine facilities that the federal government has been too lazy to build, we've tried everything.
Just to add on about the situation in Vietnam, for those who don't know, its facing a huge surge right now, in fact the hospitals are so incredibly overwhelmed, people in some neighbourhoods of Ho Chi Minh (the epicentre) and some other parts aren't even allowed outside for anything. About 300 people are dying almost every day. Food is delivered and essentials are provided from the government but it still leaves many people with not enough. People from the informal economy literally cannot afford anything because they have no income and can't work at home. My friends know a few people who would go like 50km into the city every day and sell whatever veggies they have growing in the backyard, which was
just enough for them to get by. They were able to get by all those years, because it sustained them. Now, many like them are left with very little support because of an inadequate welfare infrastructure in the country. I don't know much about politics but it kinda urks me when colleagues at work would complain about "breathing but barely living" and "Melbourne is a laughing stock in the world." "Melbourne is the most lockdown city in the world." And my favourite "Australia's the only one going under lockdown all this time when every other country have moved on".
Increasingly, while I do still (would like to) believe in the goodness of humanity, the pandemic has highlighted just how common this attitude is among the general Australian public. We're so privileged to have things like welfare that we almost just take it for granted, including measures/facilities to stop a virus that could potentially kill us(??). I usually respect people's views but it's just hard not to notice the entitlement of some people, particularly those who support the anti-lockdown movement and believe our lockdowns have been infringing on their human rights (to be dicks).
Anyway, rant over, I'm just so tired of being surrounded by people (who mean well) who get their newsfeed from a block of text on their instagram from some personal fitness instructor this whoole lockdown lol

at first you practice some patience and wait it out, and then you begin to realise that it's a limited supply after hearing it over and over. We have so much to be grateful of yet we act like we deserve everything even during a global crisis. It's so deeply saddening to see.
