From what I’ve read of the Xtreme saga, the parent company assigned as “supervisors” to oversee the bullet making people who couldn’t spell “bullet”, let alone understand the details that make a product good or bad. That led to bad things, including slowdowns in production.
Ramped up prices sounds like another parent company attempt to increase profit in the wrong way.
To build on the grocery store analogy, the most successful grocery chain in my area is very good to its employees and also offers very competitive pricing. They can do this through two things: attentive and intelligent management, and lots of volume. You can go broke trying for volume without good management, and you can go broke providing great management that can’t manage the volume to pay the costs. You need to get the right balance.
The “secret” to big business is actually just understanding the actual business you’re in - from the single purchase customer to international levels of supplier networks, and everything between. Running a business for short term shareholder profit alone is a great way to find yourself looking for work pretty quickly.
