There's nothing inherently wrong with businesses going bust and jobs being destroyed so long as there are new ones created and people can be helped into them. What are the chances? Large parts of the country haven't recovered from what happened in the 1980s. The concentration of wealth in the south east has led to massive overcrowding and general unpleasantness. What makes anyone think the Tories will do anything about it this time?
They say markets hate uncertainty, well what about people with homes and families? Are they all just expected to relocate to London, rent a room in a smelly flat for an extortionate fee and 'crack on'?
Trade off some fleeting prosperity/luxury in exchange for some stability and sustainability ... that's just a sensible thing to do.
