Black Plague had a time limit, they didn't know it at the time but although it's still with us it's not the killer it was 100 years ago.
If new variants became worse then governments have the power to reinforce rules as needed. Even though we have disgruntled people who hate government rules the vast majority of people here follow the rules for their own safety so re-introducing any rules will not be an issue if it's proven they are needed. Our vaxx rates are something like 98% double vaxxed and 88% triple vaxxed, although kids are lower, but isolation rules are stopping all sorts of things from happening. Something like 75% of all workers in isolation are there because they are close contacts who test negative to the virus. It's causing food shortages, hospital shortages, trades shortages and while many areas are struggling to get labour many are still loosing their jobs. With regular testing, sensible isolation and vaccinations we can fix a large portion of those problems.
The media keep telling us that schools all over the country are shut, kids are all coming down with the virus and record numbers of teachers are also getting sick. But the truth is there are more than 1500 government schools in this state and the most that have been shut at one time since January is 12. 14M RATs (rapid antigen tests) have been handed out to school kids, however something like 85% of kids who have been into forced isolation haven't contracted the virus.
