It's not pathetic, it's a collection issue. Estimate the cost of setting up that regulatory framework, and the cost of that reporting on the businesses themselves, and you'll quickly understand why it hasn't been done. Even the cost of estimating, is itself a cost. Without proper awareness of the issue and incentive to fix, a lack of that information isn't anything other than a natural consequence of reality.

They were aware, and the incentive to fix was there. There have been consistent and sustained attempt to cover up these issues for decades, because of sheer greed.

So greed was the strongest incentive? That means they weren't properly incentivized.
