I suspect this is a rhetorical question, and what you may be saying is, "It's ridiculous that large swathes of business needs to be told this thing over, and over, and over again, and yet they will not learn."
That is my slant on this, because I observe that often times, the incentives in organizations are to do the wrong thing that leads to the local optimum, where we define "local" as, a particular manager's well-being.
If a manager is rated by the measured productivity of their teams, the will hire for the ability to make the number and manage to the number, regardless of whether the number reflects the overall good of the team or organization.
As they say, "You show me a metric, and I'll show you a game."
In a dysfunction organization, everyone can be individually aware that the organization's management is dysfunctional, but it can't be changed without an overwhelming majority of managers simultaneously cooperating.
Not only that, but some managers actually do better by "quelling rebellion" and enforcing the dysfunction. They will actively undermine any effort to organize change.
You don't need people to be ignorant of things like this, you just need people to be attached to their individual incentives, and you need a culture where those who try to make change are rejected by the host culture.
