The capitalist form of production is tyrannical. The Capitalist that sits at the head of the company dictates to the workers. The socialist form of production frees the workers from their dictator.
Okay, first off....

nobody is forcing anyone else to work for the dictator.
Secondly, go back to the barter system. Everyone controls his or her labor and exchanges the value produced from that labor for something else that is valuable. The hunter exchanges the meat and skins he obtains from his hunt. The tailor exchanges work done sewing clothing for the hunter for meat.
No governing body should control the individual's labor BUT the individual. Likewise, nobody should govern the fruits of the individual's labor but the individual. If the individual is forced to work for someone else, that individual is exchanging labor for money/resources.
This is all basic and elementary. If the "dictator" wants to be an ass, don't work for him. The lie that the commies tell you is that you don't have a choice.
