Where are the workforce going to come from and where is the housing going to go? Inevitably the main parties are going to make big promises on staffing the NHS, on getting teachers into the classroom, police on the streets, solving the housing crisis etc but how is this going to happen? Education reform (if anyone is brave enough) will take a generation to have an effect. There is a global shortage of health and social care workers so we can't import them. So what is the answer?
