Disease is largely a consequence of poverty and of governments being unable or unwilling to undertake the public health measures necessary to eradicate them. England in the nineteenth century was also a very unhealthy place, but the government gradually invested in clean water, in the proper treatment of sewage and effluent, and, eventually, in an effective health service. Improved health and life expectancy were not the cause of England’s economic success but one of the fruits of its previous political and economic changes.
