I think you need to give some appreciation that the economy is important. Its now summer and the virus transmission should be controllable with some measures. If you keep tanking the economy the government will have to keep printing money. So follows hyperinflation and we are all screwed. I think the high risk need to keep shielding and those people need some financial help from the government. The rest of us need to be back working in offices if so needed with a national whistleblowing scheme where employees can report employers for not incorporating distancing and such safety measures.
That's the point it's not and the measures are still not good enough. Health and the economy are not at different ends. We can have both acting together. It's not a stand off between the two or take it or leave how ever hard the government are trying to make it. The longer we stay in this the worse it will get for them both. I'm happy for the economy to open up what it should look like and how it should be rebalanced, which part's are in need help is a very a different debate. We can open things up with the right measures in place following the right science together with the right public health information. The problem is the government and most of the Westminster bubble don't understand even now is this situation is not about being popular the virus is not bothered about any of that. But it's about doing what's right and going it quickly by going that the economy and public health can be protected.
As for keeping the high risk shielding it depends what the government want class as high risk. As they move that around when it suits what ever other risk factors you may have it's clear that as with other diseases. The one thing you don't want to be with Covid around is poor so that put plenty of the population higher up the risk tree. If we shield them till this is over well the economy will be truly bust.
