arms, and rightly so. The Consequences of our Inaction The toll of all this neglect is enormous. In the trouble stored up over the years as minor problems become major ones. The extra physical healthcare necessitated by mental illness costs the NHS a further 10 billion a year, according to the London School of Economics. It costs almost 2.5 billion in replacing staff who are unable to continue at work. And it costs 15 billion in reduced productivity. That's almost 26 billion a year. Or 71 million each and every single day. And think how little we talk about this major burden on business. Costs our economy cannot afford. So mental health is an economic as well as a social challenge. Our failure to act is a national failure. It's one we must put right if we are to be a One Nation Britain, where everybody has a stake and we build shared prosperity. One Nation So can we do it? It is often hard for a country to admit that the time has come to confront new problems. Particularly when economic times are difficult. But our country has faced these kind of challenges before. Major unaddressed challenges that affect the whole country. Challenges that seem to too big to overcome. It was true in the 19th century. The speech that Benjamin Disraeli used in 1872 to launch the idea of One Nation was, in fact, about sanitation. He called upon Britain to rise to the challenge of public health.
