The idea that we can make the poor better off by making the rich worse off suggests a community fund to make up for the shortcomings within society, as a social liberal would describe it – in their eyes a type of atonement. It's not a new idea, even if they follow a debased version of it excluding plague prophylaxis but instead turning to physicians for remedy after the fact.
The Bible does mention common funds but they are never controlled by a headcount except insofar as contributions are concerned. And unlike the socialist idea where everyone pays in a different amount (according to their means) God spells out a very different assessment method.
Exodus 30:12c-16 When thou numberest them, that there be no plague among them when thou numberest them, this they shall give: Every one that passeth among them that are numbered, half a shekel after the shekel of the sanctuary; an half shekel shall be the offering of the LORD. Every one that passeth among them that are numbered, from twenty years old and above, shall give an offering unto the LORD. The rich shall not give more, and the poor shall not give less than half a shekel, when they give an offering unto the LORD, to make an atonement for your souls. And thou shalt take the atonement money of the children of Israel, and shalt appoint it for the service of the tabernacle of the congregation that it may be a memorial unto the children of Israel before the LORD, to make an atonement for your souls.
Communists seek to replace God with doctrinaire institutions and to drive a wedge in wherever His Perfect Ideas bind us together, to drive us apart. They don't declare themselves to be Marxists or Stalinists at first or even use words like "commie" and "collective-ownership-of-the-means-of-production" but we know that's what they mean. The rich giving more and the poor giving less (to support their profane redemption scheme) is a dead give-away.
The Bible also explains that poor people can sometimes be lifted up, even to great riches or other forms of influence as a conduit for God's blessings to reach others. God can just bless people directly of course but sometimes chooses individuals to be His instruments in exactly the way Mother Teresa was not.
I Samuel 2:6-8 The LORD killeth, and maketh alive: he bringeth down to the grave, and bringeth up. The LORD maketh poor and maketh rich: he bringeth low, and lifteth up. He raiseth up the poor out of the dust, and lifteth up the beggar from the dunghill, to set them among princes, and to make them inherit the throne of glory: for the pillars of the earth are the LORD'S, and he hath set the world upon them.
Making rich people poor, or lining them up and shooting them for that matter, just makes everyone worse off.
