Communism

Capital is made up of dead labor and raw materials, it isn't something shared by the Capitalist and Worker. Instead, it's vampiric in the sense that ownership by the Capitalist allows said Capitalist to exploit living labor.

Commodities trend towards being sold at their values, not below or above, over time, yet profit is still taken. This is due to the laborer working for more hours than they are paid. Ie, if they create 50 dollars of Value in 4 hours, yet recieve 50 dollars for 8 hours labor, then they are working 4 hours for themselves and 4 hours for the Capitalist.

Reading Wage Labor and Capital followed by Value, Price and Profit can help explain this further, in much more detail.
