I wish we lived in a world where governments could implement a system to reward people that stay Covid free. We see huge amounts of money being send to people for economic boosters and social grants being paid, but no incentive to reward people that adhere to the rules and those that are staying Covid free.
Now I know a system like this will have several "loopholes" and negative implications too, because some people will try to exploit it ..by not getting tested and walking around infecting others.. to get this reward. (To prevent this, people might get regularly tested before the reward is paid out... but that would cripple the medical industry)

Currently nothing is done to incentivize people to stay Covid free.... just the fear ... but even that is not enough. (Most young people think Covid only kills older people, so they just ignore the rules to stay safe)
Let's debate this for a while and look at ways that this might work. #(Merit goes to people with the most constructive posts)#
This is possible to do but it will need a lot of resources and efforts for this to come into fruition. The first obstacle here is to attain a high accuracy rate when obtaining information with each person as to what their current status was and this would be the root of all before we can decide what to do next. Secondly as what you implied "exploitation" which can be a problem when we are distributing the rewards since there would always be corruption that would take place when this kind of event is happening. Thirdly, same as I said on the first we need a lot of resources for this one though the government would have a certain budget for this kind of events, the required resources for this one is surely of no joke.
