@OP
Unreliable => TVM. Squeezing the suppliers. No Quality Control.
Defect ladden => Last minute changes. We don't follow the design process. Managers overrule the engineers.
overpriced => Greed. A way for managers to compensate for their failures (sell less, but more expensive, so the books don't look so awful).
In a nutshell, we make design mistakes (more than we should), we buy cheap parts, and compound it by overpricing our products, because BF/JF have no clue how to run a company.
