The dirty truth about being an engineer is that the managers call shots like this. Cf. Boeing Max 8. No engineer wants to build crap. In a small design problem it can be bad engineering but in a huge systemic problem, or one which goes on a long time, it comes down to management. Hiring incompetent engineers ( e,g. age discrimination, H1Bs etc) who don’t push back is also is a management decision with predictable consequences.
Same for blaming the manufacturing line or labor.
Management can demand quality or demand you let go and push out crap.
Making management look good and reinforcing their promises/stories/lies is job 1.
But if the product gets on the evening news, management is going to point at "first hired, first fired" engineers, their expendable overhead.
The ones who suddenly become surplus to requirements when a prototype is finished, after cutting corners to meet a deadline.
