The needs of a people do evolve, however slowly.
One opportunity your excellent article misses is the notion of engaging the private sector in the provision of meaningful services. If there is a group of people in the world who can be expected to struggle with a problem, is that not the reason for a business to thrive?
Like an Aesop fable, when we pay for government with taxes the urge is to push back. When a business provides us a service, we approach it with a sunny futurism.
When we can learn to sidestep the moral hazards, then the profit motive seems more interested in adapting to changes, than a governing force which conflates service with authority.
