It’s really not. The core aspect of capitalism is ownership of private property. Whether I hire someone to help me deploy that capital successfully is an implementation detail.
The workers are jointly de facto responsible for using up inputs to create outputs, so they should be held legally responsible.
But workers don’t want the responsibility, that’s why they seek out employment from someone who will take that responsibility. If they wanted the responsibility, they’d start their own private venture instead.
The responsibility should be on the property owner. They own the inputs and the outputs, so they’re responsible if something goes wrong. That’s the main problem with our corporate model, those in charge (capital owners) are largely immune from the consequences of their actions. If we put execs in jail if they knowingly allow sale of unsafe products, the system would self-correct. If the worker is jailed instead, that just encourages a system of scape-goating. The worker should never be legally culpable for following orders, that responsibility should lie on the owner of the capital.
Coops provide stable jobs not pay.
They provide neither, what they provide are organizations where workers have a say in how things are done. Stability is not on the list whatsoever. However, since workers have more of a say, they can help make decisions to improve stability of both, so workers feel more empowered and interested in the future of the business.
Unions provide stable jobs and pay. Salary positions provide stable pay, but not stable jobs.
