If the last five years have taught us anything it’s this: the fact that something being unimaginable doesn’t mean it isn’t going to happen. So, it’s worth considering the prospect that Donald Trump becomes President after the 2024 election whether by getting enough votes to win the Electoral College under the current rules, or by having a Democratic victory overturned. Trump has made it clear that, in such an event, he would wish to secure at least a third term in office and perhaps a life presidency.

… but the real decisions on Australia’s emissions are happening elsewhere. That’s the title of my latest piece in The Conversation. Key paras

The Morrison government, partly through its own doing, has almost no control over Australia’s emissions trajectory. The real decisions on that are being made elsewhere – by state governments and civil society, or outside the country altogether.

Morrison’s last-minute reach for a 2050 net-zero target is almost entirely symbolic, as was the Nationals’ resistance to it.

A lot of discussion around “living with Covid” starts from the premise that, as long as vaccination rates are high (say 80 per cent of the population), we don’t need to worry about high case numbers. That’s because vaccinated people are less likely to suffer bad outcomes (hospitalization and death). The problem with this claim is that, because the primary function of vaccines is to protect against infection, unvaccinated people will be over-represented among cases. Let’s try some simple arithmetic.

Suppose the vaccination rate is x%, and that vaccination gives y% reduction in infection risk and z% reduction in bad outcomes (hospitalization and death) conditional on infection. Denote the percentage of bad outcomes for unvaxed by b %. Assume all unvaccinated will be infected if exposed.

Then, for each 100 people exposed, (100-x) unvaccinated and x*(100-y)/ 100 vaccinated will be infected. Example, if x = y = 80%, there will be 20 unvaccinated and 16 vaccinated. That is, even though unvaccinated people are only 20 % of the population, they will account for more than half the cases.

The number of outcomes will be

b* = (100-x)*b⁄ 100 + x *(100-y)*(100-z)*b⁄ (100*100 )

Say b = 5%, z = 80%, Then we get 1.16 bad outcomes, compared to 5 in the absence of vaccination. So the good news is vaccination works,

But as a proportion of cases, things don’t look nearly so good. In the absence of vaccination b=5 % of cases have bad outcomes, but with vaccination b*=1.16/36 = 3.2 per cent, which is only marginally lowe.

So, the idea that we don’t need to worry about high case numbers if vaccination rates are high doesn’t really stand up. We have to keep case numbers down. Taking the vaccination rate as given, that can only be done with measures like mask mandates, social distancing and vaccine passports.

It seems almost inconceivable that the culture wars that have dominated Australian public life for decades could end, and with victory for the progressive side on nearly every front.  And I have made premature predictions to this effect before. 

 But consider the following list of events over the last couple of years, many in the last few months.

*  After decades of quasi-legality in many states, abortion rights have been enshrined in law throughout Australia – attempts to mobilise public opposition went nowhere
*  Voluntary assisted dying has now been legalised nearly everywhere (a bill in NSW looks very likely to be passed) – again the debate was low-key and generally civil

*  The Morrison government, backed by the Murdoch press, appears certain to adopt a 2050 net zero target, and a somewhat more ambitious 2030 target. While there will still be plenty of fights about the details, these will be in the realm of normal political dispute. Culture war denialism (even of the nod-and-wink variety) is now outside the Overton window. 

* Transgender rights are estabished in law, and attempts to whip up culture war on the issue (as with Safe Schools) haven’t been successful.

*  Despite the long and bitter battle over equal marriage, the issue disappeared almost as soon as the law was changed. No one on the right even mentions the idea that it might be reversed. Nor do we see any of the snarky talking points and bogus studies purporting to prove that the idea was disastrous.  Religious freedom laws, if they are ever passed, are likely to restrict rather than expand the existing exemption of religious employers from anti-discrimination laws (an exemption which is becoming harder to exercise in the absence of social license)

The big exception to all of this is the treatment of refugees and asylum seekers. As elsewhere it’s been a potent issue for the culture war right and one on which they have generally been successful.  

What remains of the culture wars is a kind of free-floating identity politics in which well-off university-educated people denounce others with indistinguishable lifestyles as ‘inner city elites’ and appeal to ‘real Australians’, which roughly translates to ‘people with moderately bigoted views about others, who want a free pass for this’.
