The official figures I looked at were around 55k and those are still deaths of people who had the virus not who necessarily died of it. For instance, I'm sure my relation who just died will be recorded as a Covid death as he caught the disease at hospital. However, his late stage terminal pancreatic cancer is the most likely cause of his death. So the true figure of deaths as a direct cause of Covid remains alone. And this virus is not unique in having nasty longterm effects. Flu does as well. But most people get over those. The reality is Covid is not deadly for the vast majority and death rates are fairly low for a pandemic.
Even if the population figure for the vulnerable was as high as 20% it would still make more sense shielding them than locking down the country and devastating the economy. In many countries the care home deaths amount to around 70-80% of deaths from Covid. Lockdowns are not a solution. You cannot hide from a virus. It will still be there when you go back to living normally. It just drags out the inevitable at enormous cost both financially but also in lives lost due to lockdown.
I have no contempt for the NHS whatsoever. However, I don't think the suicidal policy of lockdown was the answer to overcrowding at hospitals, especially as there wasn't the disastrous overcrowding that was predicted nor anything like the volume of deaths. And pressure occurs every year from seasonal outbreaks such as flu.
There are lots of experts. There is no consensus on this among scientists. You're deluding yourself if you believe there is. There isn't 'the science' on this, there are lots of different scientists with lots of different opinions. However, you don't need to be a scientist to work out that lockdowns don't work (btw, even the WHO doesn't recommend them). You just need basic logic.
All containment will fail. The harshest lockdown outside of China was Peru and that has one of the highest death rates. Lockdowns could only work in the short term and they could only ease pressure on health services not stop the inevitable spread of the virus. Limited and targeted shielding can work. We didn't do that.
Yes, old and sick people matter which is why I recommend a policy which will actually help them. In or out of care homes the vast majority of people who died were very old and sick and we did little to help them. Devastating the world economy will create a level of poverty which will kill a great many more people than Covid ever will.
