Combined with the theory of surplus value, why capitalism's "freedom, democracy, fairness and equality" is false?

the surplus value of capitalist society is based on the relationship between exploitation and exploitation of employers and employees. The so-called "freedom, democracy, fairness and equality" in capitalist society is just their mask, a way to attract workers and stabilize the mentality of the tired. In the process of cheating, the surplus value of workers is defrauded to achieve the continuous increase of their capital. They squeeze the blood and sweat of workers for material enjoyment, and their lives are far from those of ordinary people, and they simply cannot achieve what they call "freedom, democracy, fairness and equality."

Besides, it's the same now. Factory owners are also using their employees to create surplus value for them to achieve their material enjoyment. This can't blame social injustice at all, but people's minds are different, which leads to the relationship between leadership and being led. The slogan of "freedom, democracy, fairness and equality" is just deceiving the working people at the lowest level of society. Without these people to create surplus value for them, can they spend a lot of time, eat and drink, and travel? The answer is impossible. For the working people living at the bottom, their greatest satisfaction is that they have a similar house in the countryside, and they can eat and drink, but they don't dare to expect too much from the daily behavior of the rich.

In short, there can never be a fair society, so it is false to say that capitalism is "free, democratic, fair and equal".
