Surely by 2021, the world economy will be better because they are currently working on vaccines to prevent the COVID pandemic 19. Over the next year, the government will roll out economic stimulus packages to make the economy more productive. economics goes up and gets better.
While I am hoping this happens and the economy improves at the same time I do not really have a lot of faith this is going to happen, the crash in the real economy was simply too big and it is not realistic to expect for the recovery to happen in a single year, this means the economies of the world will be susceptible for a long time after the pandemic ends, this will not be a problem if they were in good shape but with most governments being heavily indebted and the stock market being a giant casino if anything negative hit us during that time this could cause another major economic crisis in a heartbeat.
