I am with you OP.
This is because I have lost one 51 year old colleague who was a bit overweight.. (16/18) and a fit healthy 42 yr old neighbour with 2 young children earlier this year..
The last lockdown DID work.. it stopped the NHS from being overwhelmed. Because that will have a catastrophic effect in ALL suck people not just Covid sufferers. .. and that was late spring into summer and still killed 630 nhs workers. We are now in a MUCH worse position because we are Autumn going into Winter and the normal cold weather respiratory illnesses haven't even begun yet.
Everyone wants the impossible. You CANNOT control this thing by trying to be all things to all people.
The ONLY way to do it is a probably a series of two/three week TOTAL lockdowns that are enforced with draconian sanctions for rule breakers. Schools, Universities closed. All non essential shops.
This is the only way. The government has to be honest about how much money their is.. and pump it into the benefit system/furlough in these times. Make some big decisions. Like cancelling Trident (or whatever it's called these days) that would pay for it in one fell swoop.
Mortgages frozen for those without work. Rents paid for those without work. Benefit paid a a living wage.
Or
Do nothing. Accept that the death toll will be in the hundred thousand range if not more. Some of those from Covid but many many more from other diseases unable to be treated.
This is not something that can be handled in such a wishy washy way.. because it will kill so many people that the businesses won't be able to function anyway because the staff will be too sick to work and the customers will be too scared to go out or be dead.
It's a numbers issue. Pure and simple.
How many are going to die of suicide from a lockdown and loss of business /family contact ? Vs How many from Cancer, Heart disease, Covid, Flu and Pneumonia with overwhelmed hospitals and reduced staff. ?
