I think a big part of the issue here is semantics.
'Value/valuable' is a highly emotive word which most of us use conversationally to talk about our friends, families, people who have contributed to society, and so on.
But it's also one which is also used in specific clinical decision-making contexts, which have to be by their nature highly pragmatic and devoid of emotion.
Same word, different meanings. Or at least contexts. And rightly so -- otherwise healthcare systems would struggle to make practical decisions on anything.
A friend of mine has a life-limiting condition. She's the same age as me (well, give or take a year). Her condition is reasonably well-managed and there are a lot of treatments she receives and is entitled to.
There are also other treatments, for other illnesses, that I would get that she wouldn't, based on expected clinical outcome. Ultimately in certain contexts the 'system' will place a higher treatment value on my life compared to hers, because statistically I'm likely to live till I'm 80-something whereas she won't see 50.
The 'system' doesn't care about all the valuable things she's done in her life, or the questionable decisions I've made in mine. Or vice versa. The decisions are made purely on a basis of statistics, risk, and likelihood of outcome.
The semantic difference between clinical value and what we might better term worth doesn't mean that she's a less valuable person than me in a broader societal context, and to her loved ones (which include me, her friend).
I think a lot of people in the Big Questions audience, in the press, and here are eliding the two things.
