"All socialism involves slavery.... That which fundamentally distinguishes the slave is that he labors under coercion to satisfy another's desires. The relation admits of many gradations. Oppressive taxation is a form of slavery of the individual to the community as a whole. The essential question is -- How much is he compelled to labor for other benefit than his own, and how much can he labor for his own benefit?"

--Herbert Spencer, 1820 – 1903 English philosopher; prominent classical liberal political theorist.
