Was it not the case, though, that the individual involved in the DCR incident was a senior figure of some sort within the company? Much like West Coast, you have to wonder whether a person who has a vested interest in finances and profit is an appropriate figure to also be overseeing day to day operations, particularly aspects of safety compliance and associated costs. In the bus & coach or haulage industries, the rules of play are enforced by the Traffic Commissioners, who have the power to (and frequently do) take a range of measures against those who fail to comply. One such measure is to prevent unsatisfactory individuals from acting in certain roles which place them in charge of a company and it's operations. This action can be temporary or permanent. I do wonder why the railway appears far less able to act robustly and quickly in similar circumstances.
