I actually think the UKs plan is more likely to be detrimental to the economy than shutting everything down early. Businesses are already struggling as people self isolate, wfh, stop going out as much etc. If you think that lockdown right now for 4-6 weeks will resolve the problem with the virus for good then surely that is better for the economy than the current UK plan of making small changes a bit at a time and delaying the peak. So I don't really get the argument for it being about money.
If the CMO/CSO get this wrong then they will be on the chopping block, as well as Boris, I really don't think they are all conspiring just to protect the economy. There are too many complex factors involved and I would expect the CMO/CSO of the UK to have the best knowledge on the UK spread of the virus. I do think there are some people who are so anti-boris that they just always look to blame him for everything. EVERYTHING. If he ignored the CMO advice and just did what he wanted people would blame him for that too.
I can understand there may be different ways to try and control a pandemic. There are a number of medical experts that are agreeing with the uk plan, many don't. I think this is the conflict, the experts don't agree.
The UK plan does make sense if they time everything correctly. I do see the risk, and I do understand the worry. But even if we were in lockdown I would still be worried about second waves and what the death rate will be long term. There is no risk free plan and no guarantee the virus can be stopped, not now.
At the end of the day we won't know for many, many months if there is one approach that has worked better than others.
