All labor that uplifts humanity has dignity and importance and should be undertaken with painstaking excellence.
Martin Luther King, Jr.

A wise and frugal Government, which shall restrain men from injuring one another, which shall leave them otherwise free to regulate their own pursuits of industry and improvement, and shall not take from the mouth of labor the bread it has earned. This is the sum of good government, and this is necessary to close the circlue of our felicities.
Thomas Jefferson

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

Learning without thought is labor lost; thought without learning is perilous.
Confucius

Labor to keep alive in your breast that little spark of celestial fire, called conscience.
George Washington

It is only through labor and painful effort, by grim energy and resolute courage, that we move on to better things.
Theodore Roosevelt

It is essential that there should be organization of labor. This is an era of organization. Capital organizes and therefore labor must organize.
Theodore Roosevelt

The end of labor is to gain leisure.
Aristotle

It was the labor movement that helped secure so much of what we take for granted today. The 40-hour work week, the minimum wage, family leave, health insurance, Social Security, Medicare, retirement plans. The cornerstones of the middle-class security all bear the union label.
Barack Obama

Capital is dead labor, which, vampire-like, lives only by sucking living labor, and lives the more, the more labor it sucks.
Karl Marx

The product of mental labor - science - always stands far below its value, because the labor-time necessary to reproduce it has no relation at all to the labor-time required for its original production.
Karl Marx

The more the division of labor and the application of machinery extend, the more does competition extend among the workers, the more do their wages shrink together.
Karl Marx

Machines were, it may be said, the weapon employed by the capitalists to quell the revolt of specialized labor.
Karl Marx

There is no expedient to which a man will not go to avoid the labor of thinking.
Thomas A. Edison

I have read in Plato and Cicero sayings that are wise and very beautiful; but I have never read in either of them: Come unto me all ye that labor and are heavy laden.
Saint Augustine

I am afraid that the schools will prove the very gates of hell, unless they diligently labor in explaining the Holy Scriptures and engraving them in the heart of the youth.
Martin Luther

The man who has the will to undergo all labor may win to any good.
Martin Luther

The gods had condemned Sisyphus to ceaselessly rolling a rock to the top of a mountain, whence the stone would fall back of its own weight. They had thought with some reason that there is no more dreadful punishment than futile and hopeless labor.
Albert Camus

Fires can't be made with dead embers, nor can enthusiasm be stirred by spiritless men. Enthusiasm in our daily work lightens effort and turns even labor into pleasant tasks.
James A. Baldwin

Labor gives birth to ideas.
Jim Rohn
