"I remember my first reading of The Communist Manifesto, which Marx and Engels wrote when they too were young radicals; Marx was thirty, Engels twenty-eight. "The history of all hitherto existing society is the history of class struggle." That was undeniably true, verifiable in any reading of history. Certainly true for the United States, despite all the promises of the Constitution ("We the people of the United States ..." and "No state shall deny ... the equal protection of the laws")."
