"Change the economic base and you will..." - Quote by Karl Marx

“Moments are the elements of profit”

“If one wants to be an ox one can easily turn one's back on hum suffering and look after one's own skin.”

“Necessity is blind until it becomes conscious. Freedom is the consciousness of necessity.”

“It is absolutely impossible to transcend the laws of nature. What can change in historically different circumstances is only the form in which these laws expose themselves.”

“If you ever hear yourself or anyone you care about starting to express the belief that a problem is permanent, it’s time to immediately shake that person loose. No matter what happens in your life, you’ve got to be able to believe, 'This, too, shall pass,' and that if you keep persisting, you’ll find a way.”

“To do the same thing over and over again is not only boredom: it is to be controlled by rather than to control what you do.”

“Is there any man here or any woman, let me say is there any child here, who does not know that the seed of war in the modern world is industrial and commercial rivalry?”

“What a benefit would the American government, not yet relieved of its extreme need, render to itself, and to every city, village and hamlet in the States, if it would tax whiskey and rum almost to the point of prohibition! Was it Bonaparte who said that he found vices very good patriots? "He got five millions from the love of brandy, and he should be glad to know which of the virtues would pay him as much." Tobacco and opium have broad backs, and will cheerfully carry the load of armies, if you choose to make them pay high for such joy as they give and such harm as they do.”

“Perhaps the greatest social service that can be rendered by anybody to the country and to mankind is to bring up a family. But here again, because there is nothing to sell, there is a very general disposition to regard a married woman's work as no work at all, and to take it as a matter of course that she should not be paid for it.”
