Religion.
The explanation given in your question explains the meaning of Marx's famous line that "religion is the opiate of the masses." The full quote of what Marx said goes like this (in translation from the original German): "<span>"Religion is the sigh of the oppressed creature, the heart of a heartless world, and the soul of soulless conditions. It is the opium of the people."
</span>
What Marx meant was that the promises of religion were used to keep the poor from fighting against the gross inequality that favored the upper classes. Religion taught them to put their hope in the next life rather than in this life. He compared that to the way a drug user (of a drug like opium) finds comfort and escape through drug use, even though the drug doesn't really solve the problems of his present life.
<span>The word “Holocaust,” from the Greek words “holos” (whole) and “kaustos” (burned), was historically used to describe a sacrificial offering burned on an altar. Since 1945, the word has taken on a new and horrible meaning: the mass murder of some 6 million European Jews (as well as members of some other persecuted groups, such as Gypsies and homosexuals) by the German Nazi regime during the Second World War. To the anti-Semitic Nazi leader Adolf Hitler, Jews were an inferior race, an alien threat to German racial purity and community. After years of Nazi rule in Germany, during which Jews were consistently persecuted, Hitler’s “final solution”–now known as the Holocaust–came to fruition under the cover of world war, with mass killing centers constructed in the concentration camps of occupied Poland.</span>
