It's only in the last couple months that things have been different, and bear in mind only two states have any lockdown orders at the moment. It sucks that our federal government fucked up acquisition of vaccines but at this point it seems silly to not just wait a few months to reach high levels of vaccination rates before opening up properly.
We don't have enough vaccine to do that yet. We have a shortage and consequently we are in 'a race' to get a somewhat limited supply of jabs into arms before the delta strain gets out of control here and starts killing folks like it's the peak in America.
I would say, Australia cares more about it's citizens than in America. But there are definite downsides, like for instance, we don't produce Pfizer or have the very strong industrial/tech base (and the good jobs that go with it)
So it's absolutely insane to see that for the same or less daily Covid cases/deaths, Australia is going into lockdowns and imposing draconian restrictions. That's the disconnect between for many of us. At least in the US, any politician even suggesting such measures nowadays would be politically crucified.
