The benefits of the London and the South East economic hot house are not all one way benefits, and the regions have benefited too, certainly in my working life. Look at all the jobs that were moved out of London to Wales and the West (could give other regional examples), by both the private and public sector to places like Wales, e.g Fords to Bridge end (kept Sunny Jim happy), Lloyds Bank to Bristol (and Worthing!!), DVLA (centralisation benefit) Tax Offices (centralisation benefit), Aerospace jobs moved to Bristol (centralisation and merger activity). I could go on, but perhaps in the final analysis you should consider this rather rather stark statistic, percentage of public sector jobs of total employment in London and the South East is 16%, and in Wales 27%.

Mind you both private and public sector learnt a lot from these experiments of sending work out to 'cheaper' areas, its called off-shoring these days. In which case there is little or no economic or employment benefit for the UK.
