It is wrong to use mechanical feeding to benchmark residual value. As a capitalist class, the boss's capital is divided into two parts, one part is used to purchase labor force, and the other part is used to maintain the value of labor output, such as equipment, site, material costs, etc. Therefore, the mechanical feeding method allows the labor purchased by the boss to produce more value, and the surplus value is based on the squeeze of "labor and return are proportional".
To borrow a passage from "Das Kapital": "If there is 10% profit, capital will be used everywhere; if there is 20% profit, capital will be active; if there is 50% profit , capital will take desperate risks; for 100% profit, capital will dare to trample all human laws; with more than 300% profit, capital will dare to commit any crime, and even risk hanging. "In fact, the boss wants to do nothing. There are restrictions on squeezing the surplus value of labor force, but due to the protection of employees under the Labor Law, capital can only limit this squeeze within a certain range, and the main reason for mechanical feeding is to make oneself better to squeeze employees, but these are narrow-level statements.
If from a broad perspective, when the boss buys labor, most of them have rules first and then generate value. If the boss purchases a labor force, then the wealth created by this labor force must be higher than that of the boss. The cost of purchasing labor force, and the generation of surplus value, is actually based on the "cost of purchasing labor force". If there are no labor law restrictions, then bosses and companies will find ways to keep the labor force in a "high-intensity, overloaded" working condition , thereby further allowing employees to produce value that exceeds cost, and this method and time are called residual value.
Taking the two theories of 996 and compulsory overtime currently advocated, they are actually trying every means to squeeze the surplus value of employees. Based on the existence of the Labor Law, most companies dare not go too far, so they put forward this theory and then require "employee voluntary" methods to exploit employees. The purpose of mechanical breastfeeding is to turn this short-term squeeze method into a "sustainable squeeze method."
