It's worth noting that whilst the cost of producing something in the private sector is cheaper than the public sector, the cost of the public sector acquiring something from the private sector is orders of magnitude larger than the cost of doing it in the private sector. I always think it's rather odd that people who propagate the idea that the private sector can do things much better than the public sector simultaneously need to believe the public sector is better at negotiating contracts in order to believe that contracting out work makes sense. I think the key here is that the British government have reproducibly found of way of creating high quality sites. That should be examined, embraced and extended.
