The first group cares about the policy. They benefit from it. They’ve organized themselves around it.
The second group cares about stability. They have limited bandwidth, and they’re not particularly interested in reconsidering everything, all the time.
The third group doesn’t care that much.
And the fourth group is harmed by the policy, either directly or indirectly.
Change happens slowly because the first three groups have power, inertia and communications on their side.
Change happens when the fourth group can create the conditions for the third group to care, and then these two groups move the urgency up the agenda.
It makes no sense to argue with the first group.
