Real reason why the 737 max 8 crashed

Somebody should be doing a root cause analysis (5 why’s) for the real reason the 737 max 8 max crashed.

1. Why did the 737 max 8 crash? - Because there was a software design error.
2. Why didn’t the FAA and Boeing recognize the Software design error? - Because the FAA let Boeing self certify and Boeing rushed to complete the production to meet the market window and rationalized that the software was safe.
3. Why did the FAA allow Boeing to self certify the software? - Because the FAA was not adequately staffed and funded to support the 737 max 8 program they devised a program to allow Boeing to self certify with minimal oversight.
4. Why was the FAA not funded to support Boeing’s certification? - Because over the years there has been considerable pressure on all Federal Agencies to cut costs to pay for the republican tax cuts for the rich.
5. What will it take for the majority of voters to support politicians that will invest in this country and appropriately fund the FAA? - Do everything thing you can to support Democratic candidates

I know this may be simplistic but it does illustrate the point
