Want to understand the term "root cause"? It's simple.
The story of the MAX will join with Deep Water Horizon as epitomes of the end result of profit outweighing safety on the scales of corporate culture. One could add Chernobyl and the Global Financial Crisis of 2008 in the mix to include the role of regulators in the causal chain.
If you have not already seen it, you might want to rent out "Dark Waters". Takes corporate greed and regulator incompetence to a whole new level. I believe it to be reasonable factually accurate as well. (And the real background story continues).
No doubt the legal eagles will be sharpening their pencils...and although most of us like to decry "ambulance chasing" legal action and large scale compensation, it undoubtedly provides an important check and balance to the ever present reality of the consequences of corporate greed amplified by p1ss P00r regulation.
