Out of the wreckage of the Second World War, the UK transformed itself. It rebuilt its shattered economy. It founded the NHS. It created national insurance. And it helped establish international institutions like the United Nations so that the world would never endure a tragedy on this scale again. Human progress doesn’t come in straight lines. Instead, there are rare moments where transformative change is possible — where decades’ worth of progress can be achieved in a matter of months. Such an opportunity for transformative change may now be upon us. As the UK begins to emerge from Covid-19, which has cost tens of thousands of lives and over £300 billion in2020 alone, we have a similar opportunity to that which existed in 1945.
