Yes, if:
a. There still aren't enough jobs to go round - you can add Oldham, Ashton, Denton, Hyde, Stockport and probably, Bury, Wigan, Leigh and many more smaller towns - and that's just in GM. Is Rotherham thriving or Middlesborough or St Helens?
b. If there isn't enough space in the city centre to accomodate those jobs that are created.
c. If they all drive to the city centre because public transport is inaccessible (rail), appallingly unreliable (rail), slow (bus) or expensive (bus) or all of the above to a lesser extent (Light Rail).
d. If, as I said earlier all those areas become "ghost" towns.
My brother has this recurring nightmare of a post-Thatcherite state where the whole of the UK north and west of Oxfordshire is turned into a badly maintained, ultra violent 19th century theme park (a British "Westworld" if you will). That wouldn't be your idea of Utopia, would it?
