So only people who have worked in the commercial sector have a 'proper job'. I shall have to tell my friend who was deployed to Bosnia twice, Iraq, and Afghanistan, that they never had a proper job. Ditto my friend who's pretend-job it is to investigate road accidents - all that measuring of up of children's bodies after they have been flung through a windscreen is just amateur hour. And as for my cousin who works every day disrupting state-sponsored terrorism, clearly just a dilettante.
None of them have anywhere near as much real world, proper job experience, as someone who runs a corner shop.
