Companies are basically mini governments. They have leadership (CEO / President), board, etc. However they are they are not democratic. Corporate takeovers happen when an entity with lots of money buys your shares. As such, the rule of the jungle abounds, not the rule of "lets make good products" or "lets have self respect".

One thing I wish being a public company entailed was having a set of internal shares that are distributed only to the people working there, that allowed them to vote on board members / top leadership positions. For example, Amazon currently abuses its delivery staff, but I suspect this is a policy that is not endorsed by the majority of Amazon employees. In a democratic public company, there would be a feedback loop that enables the employees to have a voice.

I see this as a way of having built in regulation, where the government doesn't need to pass laws that are continuously becoming outdated but instead giving the people on the ground the ability to fight for their rights.

I don't see it as useful for small companies, but I agree that a large enough company should be forced to be public + democratic. Going from the rule of the rich to the rule of the people that work there.

I believe that the last group that tried to bring democracy to companies were... uh... after the means of production.

It sounds great in theory, but how do you deal with new hires? If you don't give them a vote, then it's slavery. If you do give them a vote, then how do you decide who to hire? If it's up to HR, how frequently do you vote for HR? Do new hires get to vote for HR?

The government had the power to approve or block mergers of a certain size but the courts in their infinite wisdom decided the only thing that matters is if the companies involved claim it will lower prices for consumers if they merge (and no longer have a competitor to fight on price...). And also the courts seem completely unable to find a way to call bullshit and learn from the history of every other merger where prices inevitably go up (because they're under less competition).
