I agree that the lives of vulnerable people are valuable but I think as a society, the longer this drags out, the more people would lose patience.
I was very pro lockdown when it started but I was also the first to go back to the shopping centres when it opened (albeit with mask) and to eat out in restaurants. As I recognized that it would probably be a year at least and I wasn't locking myself in the house for a year until the vaccine was developed.
My long awaited wedding has been postponed till 2021 (we married in 2015 but never celebrated as we were too busy saving to buy our first home). It kinda sucks.
I think as time goes by, people would lose patience with the rules and as the economic reality starts to bite, there would be protests a la Germany, perhaps even civil unrest when the furlough scheme ends. Tbh. I am more scared of that than about covid. I think we have to be realistic that covid would be around for a very long time and isn't going anywhere. Are we destined to live half-lives forever? I don't know how the government can balance infection rates while allowing us to lead relatively normal lives, but what we have now isn't sustainable.
