Have you ever worked in an American industry that makes physical products? Let me give you a hint, it's got the same pressures as software engineering but it's often harder, the environments can be twenty degrees above room temp, and the people get paid a hardly liveable wage.

You can doubt it all you want, but people are out there cutting corners like no tomorrow in pretty much every industry you can Imagine. Usually it's not the employees idea, but rather middle/upper management.

Some of the products people buy have basically never been tested. Yep. Even high end expensive equipment.

I'd say more but I'd rather not...
