My naive predictions:

- Countries are going to become increasingly authoritarian, not unlike what happened after the Great Depression

- There are going to be a lot of angry poor people looking for someone to blame and they might become violent; there might be riots, protests, or calls for revolution

- There might be a slight increase in abortions or births depending on the current prudence of couples

- Some countries might start experimenting with permanent Universal Basic Income once they realize how unnecessary most jobs have become

- Mental health and self-esteem is going to degrade (esp. in the younger generation); there might be a sharp increase in suicides or people who choose to opt out and become recluses

- We will see a very strong push towards smart cities, cybernetics, and eugenics by the start of the next decade

- Leaks upon leaks of nude media from all the random sexting going on during the quarantine

- Plenty of divorces

Following the great depression, the generation that had lived through those trying times was extremely frugal, known to keep gold and cash in matresses and other furniture. I expect that this virus will deeply affect the frugality of those living through this in a similar matter. Millions upon millions of people are out of work for an unknown amount of time. At least in the US, a massive proportion of the population couldn't even pay an unexpected $1000 expense before this.

the millenials+younger will revolt against the rent-extracting policies and regulations set by the previous ones
