Privatization

From a report made by a rail construction company in the UK:

The move to privatisation resulted in a massive loss of skill and expertise at all levels in the rail industry. In many cases, the people who were lost were the people who set the standards that form the basis of what is in place today. When these people moved on they took with them the
corporate memory which formed the decision making criteria of what was done and why. The corporate memory issue is further compounded by the disaggregation brought about by privatisation with no one body holding all the information.

So much for the idea that privatization always makes things more efficient. And this coming from a company that almost certainly benefited significantly from it. For more on this, see The Navigators, a movie about the impact of privatization on railway workers.
