Is Capitalism a Form of Labor?

According to marks, human beings like we have a kind of essential nature as creative and productive animals. We transform the world around us with these creative, productive powers. But the way capitalism works with its increasingly specialized forms of labor is that it leads to an alienated work for many people. The workers don't themselves or their identities reflected in the products or the activity of labor, right? Labor, for them is not a means of self expression in any way. And so they have this division of their life where they can only develop themselves as human beings in their leisure time or free time.
