I read something last night that chimed with me, suggesting that the government are repeating the mistakes of Eat Out To Help Out about this time last year. I.e. seeking to normalise dangerous behaviour for the benefit of the economy, ignoring the long term cost of this strategy. Even if this isn't true, masks are such a thorny issue, that there's no way they are going to even advise any kind of mask wearing again until it is already clear that the sky is falling in again.
I would also advocate mandating the use of technology to monitor air quality inside public buildings (it's 2021 - we can do better than suggesting opening a window and hoping for the best) and updating the self isolation requirements to reflect the symptoms of the current variant rather than using year+ guidance created for a variant that has long since been superceded. Both of these things would save lives but would mean enduring short term pain to avoid it in the medium to long term, so again, won't happen until it is too late.
