Capitalist could get some rewards even if they do no work because they "run the business" but this should be limited in amount & capitalist should not be taking all of the profits.
Workers who are picking up all of work once business is already established (& capitalist already got his RoE and covered all his costs) should be profiting from their own work also.
The capitalist is often still working. You dont seem to understand that producing the product only matters if the owners have someone wanting to buy that product.
Workers should also be included in all decision making so that capitalist can't just move the business to China etc, leaving lives of the workers in shatters & without income any more.
That is a horrible way to see it all. First most workers fear making decisions. They want a central figurehead to turn to, and to place blame on. One decision maker works best.
