There is always a ruling class - a group of privileged who live by a different set of rules. Those espousing communism (always liberals) imagine themselves in this group.
They also use the very base, anti-Christian tactic of creating class envy to achieve their end.
Just ask any non-ruling class person who has escaped from a communist country to the US what they think. It is the same answer over and over from all different cultures that have tried communism. It never delivers its' deceitful promise.
