“Since the labor-power could be the labor of four, eight, or even twelve hours, the amount of labor expeneded can be augmented. The value of the labor-power is decided by the consumption goods necessary to maintain the life of the worker, making it possible for that person to exist as a human being who expends the same labor today as yesterday.”

“Only when the stock of wealth can be related to human energy by purchasing living energy as "labor power", offered for sale by people who have no other means of using their labor to ensure their livelihood: and only when it can relate that labor power to purchased machines - embodiments of past transformation of nature by human energy expended in the past - only then does "wealth" become "capital."”

“The essence of capital is its ability to mobilize social labor by buying labor power and setting it to work. This requires a market in which the capacity of human beings to work can be bought and sold like any other commodity: buyers of labor power offer wages, which sellers accept in return for a commodity, their own labor.”

Eric Wolf (1923–1999) American anthropologist

“The capitalist mode acts to accumulate capital through the hiring of labor power, but is marked by the cyclical alternation of labor mobilization and labor displacement; each intake of labor power uproots some prior adaptation, while each sloughing off of labor power creates a new cohort of the unemployed.”

“Now, on the contrary, when every one is to cultivate himself into man, condemning a man to machine-like labor amounts to the same thing as slavery. If a factory-worker must tire himself to death twelve hours and more, he is cut off from becoming man. Every labor is to have the intent that the man be satisfied. […] His labor is nothing taken by itself, has no object in itself, is nothing complete in itself; he labors only into another's hands, and is used (exploited) by this other.”

“Labor is prior to and independent of capital. Capital is only the fruit of labor, and could never have existed if labor had not first existed. Labor is the superior of capital, and deserves much the higher consideration.”

Abraham Lincoln (1809–1865) 16th President of the United States

Context: Labor is prior to and independent of capital. Capital is only the fruit of labor, and could never have existed if labor had not first existed. Labor is the superior of capital, and deserves much the higher consideration. Capital has its rights, which are as worthy of protection as any other rights. Nor is it denied that there is, and probably always will be, a relation between labor and capital producing mutual benefits. The error is in assuming that the whole labor of community exists within that relation.
