And actually, they didn't really care about those people, it was just that if those people were blocking up hospital beds, 'the rest of us' were going to start dying from the normal totally treatable things that happen to us. It was really about limiting the wider impacts, not helping someone in their 80s live a other 5 years (though I totally believe someone in their 80s or at any increased risk deserves that respect and support from the rest of society, and deserves people making small adjustments to protect them)
The idea that they helped or would help the average person is/was missinformation.
It was always about preventing significant downsides to minority of people who would see a positive average benefit from lockdowns (the sickly, elderly, immunicompramised, and those likely to need medical treatment during the pandemic.)
This isn't neccessarily a bad thing in general.
However, there were several areas where the harms of lockdown policies were ingnorantlly imposed without having much benefit at all, or with insufficient consideration for the harms caused.
2. The flu is a known, covid was a near complete unknown. It's easy in hindsight to say that we shouldn't have locked down, but if the thing had mutated and wiped out half the planet, you'd be singing a different tune.
