Let me explain.

With apologies to Leo Tolstoy, every market boom is similar; every market crash is different. In Australia, this one is different from the global financial crisis, the crash of 1987, the oil shock of the 1970s, and the crash of 1929 in several ways. Those differences will most likely determine its duration, who are the big losers and who gains.

To start with, obviously unlike other crashes, this one was caused by a pandemic, not the usual case of asset bubbles and fear outweighing greed.

Secondly, Australia now has vast superannuation reserves.

Thirdly, internet and mobile phone use is now almost universal. Other than the trades, construction, logistics and personal services, almost all of the rest of the economy can work online.

And lastly, the underlying financial system is fairly sound, and certainly not as shaky as it was in 2008, 1987, the 1970s and the 1930s.

The chief investment officer of one major industry superannuation fund (among others) put it this way. For recovery to take place we need three things:

The first two conditions have been met or are being met. The third depends on Donald Trump, and whether people in his administration can neutralise his narcissism, erraticism and sociopathy. These are perhaps the three worse traits a leader in a crisis can have.

Trump's narcissism will mean that much-needed scientific advice will be ignored because Trump thinks and has said that he usually knows more about any subject than anyone else and that he is the best person to make decisions - often based on gut feel.

He irrationally described the impact of COVID-19 as similar to that of car accidents, as if car-accident victims can spread road trauma. He keeps downplaying it.

Further, it means he will act in his own interests first, irrespective of the national interest or the overall best interests of the people. His re-election will dominate his thinking. Until COVID-19 hit, the booming stock market, economic growth and low unemployment were about his only electoral assets. They are now gone.

At present, he says he would like to ease restrictions by Easter Sunday so the economy can move again and people can "go to church" - ever an eye out for the evangelical vote.

Then we have his erraticism. So often he makes decisions (leaving Syria, closing the Mexican border, firing Rex Tillerson) and tweets them almost immediately, so he can be seen to be in control. Then he often goes back on those decisions - all the time never understanding the risks or consequences.

This is precisely what is not needed in a crisis.

His sociopathy makes him the wrong leader to deal with a pandemic. Without empathy for people, he is incapable of making decisions balancing the inconvenience and economic cost of restrictions with justified fears of disease and death.

The three character traits, unless restrained, could easily become a deadly cocktail. Moreover, Trump could end up trashing the very economy he is trying to preserve. But if that does not happen before election day, he will not care.

Sadly, we are in his hands. With a more sensible and selfless president, the crisis - both health and economic - would be at the stage where we could see the light at the end of the tunnel.

The internet and mobile phones have enabled a lot of businesses and government functions to carry on.

But the big buffer is superannuation. In December 2019, Australia's superannuation assets stood at around $3 trillion (3000 billion). The government will allow people access to $20,000 from their fund. That will provide some much-needed short-term liquidity, but it has a long-term downside on the generational divide. Yet another one.

The older people get, the more they change their superannuation accounts away from growth and higher risk to lower-earning but safer strategies, either capital-guaranteed or "sustainable". Often these people have less need to access their funds. Younger people, however, will grab the $20,000 - or whatever lesser amount they have in their account.

The funds will pay them. Most funds, especially larger industry funds, have large amounts of cash investments which they can sell to meet the withdrawal demand, rather than selling shares at a low price, locking in the loss.

In effect, when people rush to withdraw their $20,000, the superannuation funds will be buying what in effect is their shares at rock-bottom prices. When the market returns, the funds overall will make a large gain. Unfortunately, that gain will go mostly to people who did not have to draw on their super in this time of financial stress. The rich get richer.

Even with that downside, Australia's compulsory superannuation scheme will go a long way to helping the recovery.

Another way this crash is different is that people are not rushing to safe investments - gold and bonds - as in previous crashes. Rather, many people who need cash to tide themselves and their businesses over are selling the safe investments because they cannot bear to lock in the loss by selling shares at such a low point.

It is as if they are assuming that once the pandemic is controlled the share market will boom back straight away, unlike after previous big crashes when the market took a long time to recover. We will see if they are right.

That will depend on whether Congress, the administration and state governors can limit the worst of Trump's decision-making. Or whether they let this man so wrapped up in himself do away with the restrictions on movement and gathering that are needed to halt the spread of the virus, in the misguided and unscientific belief that the share market and the economy will be booming at election time.
