Boeing 737 has been around for ages.  

Its basic platform has been used in all 737 models in more than six decades.  To ask Boeing to take the drastic step of remodeling the floor plan to accommodate the most recent developments in hardware would be prohibitively expensive.

That's why they chose to use software to compensate for the myriad unsafe features of the 737-8 and 737-9 models.  

That's as if you use a band-aid to cover another smaller band-aid which in turn had been used to cover a gunshot wound, when a more radical surgical approach should have been performed in order to fend off Gram-negative sepsis and shock.

The M.C.A.S software is the culprit in both accidents.

If software upgrade of M.C.A.S is the only thing that is required to make the plane safe they would have done it a long time ago even before the Indonesian incident, for Boeing knew very well the 737-8 MAX wasn't safe at all.

The FAA used to check upon the safety data of all test flights, but in the case of the 8-MAX it shirked its responsibility and let Boeing engineers do their own testing and data gathering.

That's because the 8-MAX was projected to be the biggest money-maker in Boeing's history -- accounting for 1/3 of 34 % of its yearly revenue at $30 Billion a year.

It was no accident that Donald Trump selected Boeing as one of his first presidential visiting destinations because the Aerospace giant was emblematic of U.S. manufacturing prowess in high-tech industries, not to mention its anchoring position in America's Military-Industrial Complex.

Here I am going to invoke some technical terms that you can find in any U.S. Aviator's Guide to Navigation for further studies, so I am not going to reiterate what you naughty boys and girls can do on your own.

In the case of the 8-MAX, the M.C.A.S. software takes over the control operations of the plane (in other words, activated automatically) when the Angle of Attack is high and the autopilot is off.  At this stage of the game its flaps are up and the plane is steeply turning.

Let me repeat for emphasis:  the M.C.A.S software is activated automatically when the Angle of Attack is high, the autopilot is off, the flaps are up and the plane is steeply turning.
