“[W]hen Karl Marx, the most consistent translator of the altruist morality into practical action and political theory, advocated a society where all would be sacrificed to all, starting with the immediate immolation of the able, the intelligent, the successful and the wealthy-whatever opposition he did encounter, nobody opposed him on moral grounds. Predominantly, he was granted the status of a noble, but impractical, idealist.”
