Employees at Spirit AeroSystems, a subcontractor that Boeing spun off, accused the company of disregarding high levels of defects.

This attitude is common in US businesses, and it makes life painful. We need to change the system that makes it profitable to run businesses with this attitude.

Structural reasons why Boeing is doing badly in the safety field: it's owned by banks and asset managers, its outsourcing is out of control, and the US doesn't have laws to ensure workers' safety concerns are heeded.
