But how about free universal care? It’s the most expensive option, costing another £7bn by 2021 – but that’s only £2bn (0.1% GDP) above May’s proposal. The Scots do it, and so could we. Tax rises would have to pay for it, notionally hypothecated to sugar the pill. Although this sum still only provides care at current miserable levels, it has one huge advantage: it aligns NHS and social care systems. The greatest barrier to uniting them seamlessly is that patients pay for care, but not for the NHS.
