This is very true, and it's also often overlooked that the proponents of lockdown (for want of a better expression) don't tend to advocate for lockdown as "the" measure, but always also ask for improvements to other pieces of the puzzle that could well and easily be achieved with some political will and some money (and quite possibly a lot less money than is currently being spent).
Examples being: advocating for supporting people to be able to isolate properly when tested positive (at the very least not having to go outside the home or possibly better still to support people in crowded housing to isolate away from their family). Or, quite the opposite from wanting to put more burden on individuals to keep to an ever stricter lockdown, advocating for better oversight of workplace measures, more WFH and short-term pausing of non-essential work and production. Or, better recognition and information on covid symptoms outside of the big three cough, fever and loss of smell, such as headaches, sore throat, nausea and fatigue.
All of which could aid in reducing transmission more quickly during lockdown periods and keeping rates down, and all issues which have been highlighted for months and months.
Another point on the NHS: I think I saw it linked to elsewhere on the boards, Rachel Clarke, the palliative care doctor who has been a rare prominent voice reporting from the "frontline", spoke at the Independent Sage meeting last Friday. She made a very powerful point. Not only about the terrible and traumatic conditions for staff AND patients in hospital currently, but about the ability of staff to care for patients with the whole range of health needs now and in the short- and medium-term future (see for example the massive backlog of operations).
That point has imo not had anywhere near enough recognition. Very rarely do you hear it talked about that the NHS "not being overwhelmed" has actually meant vastly expanding ICU capacity at the expense of other care, and indeed quadrupling the case load of ICU personnel. Rather than looking at how many current critical care beds are occupied with covid patients as an isolated measure, surely the question that needs to be asked is "how many covid patients can there be in hospital at all so that all other healthcare can be provided, and with a humane workload for NHS staff".
I think this is so crucial and also a point that the public could get behind, and one that could possibly bridge the potential rift in the discussion around this tricky period when a lot of older and more vulnerable people have been vaccinated. It won't be any good for the people now protected from severe cases of covid either, if cases in the under 50s should be so high that still most healthcare resources have to go towards treating covid cases, rather than other less life-threatening, but potentially still life-shortening or limiting conditions.
