I’m all for higher minimum wages, unions, paid leaves and other forms of worker protection, but it seems like the most forms of worker protection focus on maintaining a division between an employer(s) who owns the business and the employee who makes money for the business but does not own it. IMO, this division is unethical and exploitative because it denies the worker the full value of their work.
Are there any political or social movements that push for policy or legislation that makes all businesses to be worker owned cooperatives?
Generally, yes. Workers working in common are more efficient, and as such the Value created by 1 hour of Socially Necessary Labor Time for all of society is higher, which in turn is represented by increased use-value.
