Well in the case of the MAX it certainly was down to savings.

Quite simply, Boeing tried to make the 737 more fuel efficient by fitting a 2.5 metre diameter engine to an airframe originally designed for, and fitted with a 1.25 metre diameter engine. MCAS came about to avoid redesign/recertification and huge savings in training costs to their clients allowing Boeing to knock $1 million off the list price of each aircraft. Once the MCAS route was decided upon, further savings were made by including virtually no redundancy, altering trim logic and setting up a massive ‘gotcha’ which claimed 346 lives.

This was very much about making savings, as the technology and skills existed for a better solution but were simply not chosen.
