Keep in mind that at least in the Anglosphere, a point often raised about the government is that they are incompetent, that they need to be starved out, so usually
- they don't have the resources or backing to hire people who are up to date at competitive compensation levels
- the people left are those who have been able to survive such onslaught from their bosses, so they are presumably very jaded, cynical, and careful about new proposals
Our politicians do not empower the bureaucracy to be nimble, there is no reward for doing so. So I wouldn't expect it to be.
The incentives for government consultants are also generally not aligned to deliver quickly or competently.
