Yes.
There are currently proposals in the UK for the living wage to become the minimum wage. I have no idea how the government or campaigners come up with their hourly figure - but everyone agrees there should be one rate for London and a lower rate for the rest of the country., to reflect the higher living costs. There will still be regional differences that will benefit some people more than others but we are a small country and I think it would be difficult to do otherwise. We shall have to live with the resentment that, once again, London benefits at the expense of the rest.
