I know several people from my university who work at companies like Lockheed Martin and Goldman Sachs.
How could you work for companies like this? Why aren't such people socially ostracized? These companies destroy lives. Goldman is responsible for the 2008 financial crisis.
You could argue “well, they have no choice, they'll starve otherwise” this is nonsense as these people are educated often with master's degree (or further). They could get better jobs if they wanted.
