I believe in what some call "Neo-Marxist Economics", although most of us that lean in this direction more closely are aligned with where Engels was coming from (the two had a rather nasty split, and Engels felt that Marx fell off the turnip truck because Marx went on to delve heavily in the philosophical direction).
In brief, what both felt was that both owners and politicians were all too often corrupt and/or inept, putting their own accumulation of power and money to deity levels, while the workers got little back in return yet did most of the work. Therefore, why not give the power to those who did the work-- the workers themselves, and that includes all workers from top to bottom, making relatively equal wages since they all are working to make the company/collective successful. And instead of having power concentrated at the top, have much more local influence in collaboration with the workers, even to the point whereas Marx hoped that way down the road there would be no need for any national government.
Obviously, these employee-owned businesses would then compete with one another, and regulations would be minimal since taking reckless risks could jeopardize the jobs of the entire company/collective, plus each worker and each local politician would have strong incentive not to let any one person or any small group do something that could cause a collapse that could affect them all.
Some may wonder about the question of outside investors, but this process does not disallow for that but it does not allow them to be the dominant force in any company/collective. Or what about private investments? According to Marx and Engels, private ownership is allowed but not allowed to be passed on through inheritance. IOW, once the owner either croaks or decides to get out, the ownership resorts to the workers, although any siblings of the owners may be able to work for the company/collective. Again, a reminder is that it's the workers that made the company succeed-- not the siblings.
The potential benefits for going in this direction are enormous if one thinks it through some other implications as to how this would pan out. Anyhow, I stop at this point.
