It was recently reported that poor mental health costs the UK economy £70bn a year, a sum equivalent to 4.5 per cent of our GDP. This is nothing short of a national disaster, primarily in terms of ruined lives but also in terms of lost productivity and economic inefficiency.
It is also, most infuriatingly, an avoidable disaster. We know that mental health correlates strongly with income inequality, and that a reduction in inequality could significantly reduce mental health problems across the UK. But as with many of the economic and social problems associated with our high level of inequality, we seem to prefer to spend money on expensive and complicated solutions, rather than cost-effectively addressing causes. The cost of inequality can be seen measured in the billions we spend on our welfare state: on the nurses, doctors, police, probation officers, prison staff, psychologists and psychiatrists and all the physical buildings and equipment that we provide for these professionals to do their work. Poor mental health drives up the demand for all of these services and the people and assets that deliver them.
