I think that the decision to keep places of education open was purely a decision based on economics.
During the Great first Lockdown nothing opened, the majority of the country stayed at home. yet something went wrong, because the covid virus is still with us. Coming to the end of the Second (pathetic) lockdown we are now in a position of still having the virus but most people are at work to stop the economy tanking, if we were forced into a third, proper lockdown, the kids would be at home meaning the parents couldnt both go to work.
It's a balancing act for the Government. We have to have a functioning country, which means the movement of people, if we lockdown totally again, the virus might (emphasis) be stopped, but at the expense of the economy. So work continues, which means the kids cant be at home.
For what it's worth I have two observations.
Firstly, I work in construction which was allowed to continue duiring the First Great lockdown, our van was the just about the only vehicle on the road, it was astonishing. During this current lockdown it appears to be a normal day on the roads, traffic snarled up as usual.
Secondly, I live in Lincoln a very small city, we have no anti-vaxxer demos, no rioting, no masive street parties yet we are about to hit Tier Three. London is going into Tier Two. Tier Two! It is this sort of blatently wrong, being a bit easier on the capital, that makes me believe that this is now more of a Political Pandemic and not a Medical one.
I gave you a thumbs up for that.
You could also infer from your post that lockdowns don't really work.
Ok perhaps there was a justification for the first lockdown, in that (arguably), we didn't know what the virus was capable of, and there was (again arguably), the possibility of hospital capacity being overwhelmed.
So on that basis the first lockdown could be justified. Save the NHS and all that.
However, once we got through that first phase, and things started opening up, predictably the virus numbers increased, and it became increasingly clear that the hospitals were not, and are not going to be, anywhere near overwhelmed.
We now find ourselves in this limbo state of not quite locking down, not quite opening up, and not really knowing what we're doing as a country and not knowing why exactly we're doing it or not.
To stay in this limbo state, seemingly on a perpetual basis, with the vague aim of "getting the numbers down", when the way those numbers are crunched is questionable at best, is a serious indictment of the current Government.
I voted Conservative at the last GE, and could not, and cannot countenance the other lot, but ....the current administration led by a PM who looks increasingly like Bambi on ice in the face of this crisis, dancing to the tune of an overly vocal scientific/public health/NHS lobby, and aided by a compliant media is shocking in the way it is taking the country down the toilet.
The advent of the vaccine might just save BJs premiership, but he's seriously gone down in my estimation here, and mid to long term he has to go.
