I am sure you will agree that a significant number of humans will disregard ethics when it comes to personal enrichment. Let me provide one example who comes immediately to mind: Pablo Escobar (thanks, Netflix). US prisons do contain a large number of white collar criminals.

> nor do they [companies] pursue profit regardless of ethics.

This does not follow. Companies are composed of people, and people do disregard ethics.
