The only thing destroying the economy is the virus. We should get rid of it (in effect), like reasonable human beings. The shutdown saved a bunch of lives, and continues to save lives every day, even though it's over. But we should get rid of the virus! This is not complicated, and we know exactly what to do.
I think you're right about deaths being higher if this had happened 25 years ago. But I don't think there's any significant chance of society or the economy being destroyed, as long as the Fed keeps up the good work. As far as earlier times are concerned: I think you underestimate the psychological impact of hospitals collapsing with a surge of patients (which would have happened in more locations with the slower flow of information, probably), and I suspect the economic impact in prior times would have been substantially GREATER than it is now, since it would not have been possible for many to work remotely, the Fed probably couldn't stimulate as readily, and I think you're underestimating the effect those hospital collapses have on the general population.
Unfortunately I think some of the economic damage is going to be with us for a while. If the government had handled things competently, we would have put the economy into an induced coma, dealt with the virus, and brought it back. But now things have been so badly botched a lot of people are going to end up losing significant ground economically.
A lot of people were granted a few months holiday on their mortgage payments, but instead of adding the payments onto the end of the loan, a lot of lenders want several months of payments all at once now. Similar thing with other loans as well as rent owed. We could see a lot of home foreclosures, people evicted from rental housing, and cars repossessed in the coming months. Those people won't be returning to their pre-COVD spending habits for years, and possibly longer. The homelessness crisis could be severe and a big drag on the economy for years to come.
In the business sector, a lot of companies have scaled back and there are many corporate bankruptcies. There was already a big shift in economic habits going on that was hurting brick and mortar stores that accelerated with the pandemic. People are buying more than ever online and when the pandemic is over, that is unlikely to go back to pre-pandemic levels. That means a lot of retail jobs are going away permanently. Some people who are either too stupid or have high risk tolerances are going out to eat in some parts of the country, but a lot of people aren't eating out. We've been getting take out here and there, but most of my neighbors won't even do that.
When the pandemic is over, a lot of bars and restaurants are not going to be there anymore. As people become confident the virus really is gone, people will want to eat out again, but it may take years for that sector to recover.
On the other hand the supply problems with China has made people aware of the risks of depending on one supplier and some manufacturing may move back home, but it will likely utilize the state of the art in automation and as few people as possible.
China may be disrupted for a while. As I've been able to glean (getting accurate news out of China is difficult). China's economy has become unstable with some runs on their banks, and they are being hit with some major disasters. In the summer China usually gets a smaller version of the Indian monsoons, but this year is breaking all records. They normally have a month of heavy rain from mid-July to mid-August, but it started in early June and hasn't stopped. The forecast for the next two weeks is for even heavier rain than they have seen thus far.
They have already broken flooding records from as far back as 1940. The worst flood recorded in world history was in 1931 (in the same region) and they are pretty close to that, though it's hard to compare exactly because the rivers and areas around the rivers are very different from 1931. Most of their farm region is underwater and there will be little in the way of crops this year.
The Chinese have a concept called the Mandate of Heaven that basically says China is ruled by leaders who have spiritual blessing. When that blessing is withdrawn, the country is hit with many natural disasters and unrest until a new ruling order takes over. There is a lot of talk about the Mandate of Heaven around China right now. There were posters reminding people of it all over Hong Kong until the CCP made the posters illegal.
Between the natural disasters and possible political unrest spreading from Hong Kong to the rest of the country, China may not be able to supply the world with its manufactured goods for some time to come.
If the US steps up to fill the gap left by turmoil in China, it would definitely help the economy, but it will probably take a few years to accomplish, even if the US jumps on it and starts rehabbing old factories Jan 21.
