Quotes:
"In the present stage of human progress, when ideas of equality are daily spreading more widely among the poorer classes, and can no longer be checked by anything short of the entire suppression of printed discussion and even of freedom of speech, it is not to be expected that the division of the human race into two hereditary classes, employers and employed, can be permanently maintained."
--John Stuart Mill, Principles of Political Economy, 1871
"I entered Parliament with what I thought to be the lowest possible opinion of the average member. I came out with one still lower."
