What's the setence "they can develop a degree of insularity from those they are intended to serve"?
When someone in an organization tries to fix the problems of inefficiency and red tape, they usually run into people who strongly favor and defend the status quo. Resistance to change is a natural human response. In a company, opposition may come from an employees’ union or a group of senior officials wedded to privileges granted in an earlier, more profitable time. Because it can be next to impossible to remove those types, they can develop a degree of insularity from those they are intended to serve. The larger the bureaucracy, the greater the likelihood that there will be little price to pay, if any, for a lack of responsiveness.
