Just because communism also sucks does not mean that capitalism has not ruined our lives.

If the employees owned the firm, then no they are not.

Authoritarian Communism? Yup, it sucks too and I'd call that out.

I think maybe you're conflating capitalism and politics.

The need for workers to voice out against company policies and actions often necessary for safety of workers, customers, etc. This is required for capitalism to work to any standard.

Its not hard to see how firing employees for noting safety problems can cause problems. The obvious case for this is Boeing where they started punishing people for doing basic quality control work.
