“In these days, under the rule of capitalism, a government, even if it is full of philanthropy and animated by the best of intentions, can do nothing of real value to our cause. One must keep free from illusions.”

Letter to a General Pinto<!-- (perhaps ?) late 1840s-->, as quoted in ‪Captain of the Andes : The Life of José de San Martín, Liberator of Argentina, Chile and Peru (1943) b‬y Margaret Hayne Harrison, p. 196
Context: One should be under no illusions as to the future of the Old World. The real contest in the present day is purely social. In a word the struggle lies between him who has nothing and him who has. Figure out the consequences of such a principle, infiltrated in the masses by the harangues of the clubs and the reading of millions of pamphlets.

The Liberals' Mistake (1987)
Context: All of us are responding to the fact there is no system that can keep any promises. Everybody is fighting each other under the illusion that it is the "other people" that are causing the problem. We don't realize that we are all in the same boat. We are all suffering from the absence of a system that can pull us together and assure us that the results of each person's work will come back to him and enhance his life in some way.
Neither Democrats nor Republicans today offer any vision of how we can overcome our present difficulties and build a more satisfying life. Both offer merely palliatives and, at best, a holding pattern. We have to look beyond the politicians to see a different future.
