There is a lot of debate right now in the UK about who should best be trusted to provide public services, should it be provided directly or should it be contracted out to the Private Sector. The Private Sector are the people who win Government contracts with exaggerated promises and then squabble about providing the services that they have promised and keep making menacing threats for more money.
Just this month a major Private Sector company called Carillion who enjoyed a lot of public sector contracts went bust and left the country and the tax payer in the lurch.
I feel well qualified to speak out on this matter because for ten years between 1990 and 2000 I had the misfortune to be employed in a privatised service in waste management.
