But regulation is supposed to provide an impartial set of rules that defines how people go about their buisness fairly. One of the great criticisms of regulation is that incumbents with access to government can influence the rules to favour themselves and avoid competition. Having employees of particular large companies work as beaurocrats encourages this, especially if they return to those companies. In it's early phase -- such as with these googlers in the US gov, the revolving door brings dynamism. But over time it brings stagnation because parties have an interest in making current practice the only thing allowed.
