Genuinely, whilst China is technically "responsible", they aren't responsible for the way western goverments are acting.
IF Trump gets his way and the economy can "roar by Easter" - which needs to happen, you will be ok.
Western governments have handled this poorly. You don't shut down your
whole economy and put people out of work.
There needs to be track and trace in place, enforced guidelines and clear and concise dates on when things will re-open.
The major issue atm you're facing doesn't come from China. The problem comes from people being out of work, funds being depleted and this attitude of like... "Who cares about the economy, don't you value people's lives?!"
You have people begging for
long term hardcore shut downs. The economy can't sustain that. When the money runs out and it will, it will become more dire. It doesn't matter if you run a capitalist society or a socialist society, every society needs a currency.
Even if you go as far as to say a fiat currency is not needed and you look at barter, there's still a basic structure of exchange. It's not possible to live in a society where neetbux are dispensed and people do nothing to get them. There will always be a cost to things. Limiting how productive society can be is the real killer.
In Australia, people sadly think that the government can continue to give out Coronacash until "cases are down to zero". They literally will never be down to zero. This is going to enter the regular rotation of viruses from here on out. Only herd immunity and a vaccine will reduce it to zero. They think that it's sustainable to shut down schools for a year, to restrict people to their homes until a vaccine is found. They think it's sustainable for people to be out of work for 18 months. It's not. These are the people who are more dangerous to society than the virus. They aren't realistic.
So a calm, rational approach that yes, it's deadly, it spreads more so than the flu but is
AS deadly as the flu/as much as a burden as the flu but also with a strong commitment to the economy/keeping wheels churning so everyone is able to access services they need is important. If countries don't minimize their economic damage by being rational, but fast acting, is that China's fault. It's up to you to mitigate damages.
Can China be held responsible if you don't do that? Not really.
I'm pretty sure legally blaming it all on China would hold no water, as well.
