We don't know. Covid19 leaves some people with long-term, perhaps permanent damage. You might lose working-age tax-paying people from workforce, having to pay them disability allowance, and this might offset part or all of your savings in pensions.
Yet a much lower level of infected population than conventionally understood has been reached. The models that assume the virus will continue to grow until 60%-70% have been infected are therefore wrong, reality itself is proving that.
There are now a whole lot of theories being explored as to why this is.
[edit: someone complained about the original graph link not matching worldometers. It's worldometers that's wrong so I replaced it with a Wikipedia link, which sources its data direct from Swedish health authorities. I left the lockdownsceptics link because it's a bit fresher]
I don’t know where “lockdown sceptics” got their data from but for me the current numbers look like a constant infection rate and only slightly reduced death rate that is also not falling: https://www.worldometers.info/coronavirus/country/sweden/
