When the question/topic of rejoining crops up I ask myself a few questions:
Would it improve the NHS/general health system.
Would it improve the education system.
Would it reduce unemployment by a significant amount.
Would it lower my energy bills.
Would it create more new build affordable homes.
Would it reduce waste and pollution by water companies.
Would it greatly reduce the amount of potholes in the road network.
Would it reduce 'grass roots' crime - (burglary, theft, assaults, mindless vandalism etc).
I believe the answer would be no, so what's the point.
Of course other people have a list of their own 'needs and desires'
