I am reminded of a passage from the Gospel of Matthew, which speaks about how the elite privileges its own at the expense of the many:
Jesus spoke of it first, asking, “What do you think, Simon? From whom do the kings of the earth take toll or tribute? From their children or from others?” When Peter said, “From others,” Jesus said to him, “Then the children are free".
(Matthew 17:25-26)
I believe these verses have in mind the nepotism of the ultra-rich and powerful, who find ways of exempting their family wealth from tax while gaming the system to enrich themselves at the expense of their nations.
In the first century, kings and aristocrats would use tax levies (Matt 17:25) to compelling the less powerful into pernicious debt situations (Matt 5:25; 18:23–34) that caused peasants to ultimately lose control of their land.
The Old Testament book of
Samuel actually contained a prophetic warning about the exploitative nature of royal authority, which sounds quasi-republican:
1 Samuel 8:10-22
Samuel's Warning Against Kings
And Samuel told all the words of the LORD unto the people that asked of him a king. And he said, This will be the manner of the king that shall reign over you...
He will take your fields, and your vineyards, and your oliveyards, even the best of them, and give them to his servants. And he will take the tenth of your seed, and of your vineyards, and give to his officers, and to his servants. He will take the tenth of your sheep: and you shall be his slaves, and you shall cry out in that day because of your king which you shall have chosen.
Nevertheless the people refused to obey the voice of Samuel, and they said, Nay, but we will have a king over us, that we may be like all the nations, and that our king may judge us, and go out before us and fight our battles.
In a similar way, the Tanakh prophet Amos denounced the Judean upper-classes for exploiting the poor:
Therefore because you trample on the poor and you exact taxes of grain from them, you have built houses of hewn stone, but you shall not dwell in them; you have planted pleasant vineyards, but you shall not drink their wine.
For I know your transgressions are many and your sins are great, You who distress the righteous and accept bribes And turn aside the poor in the gate.
(Amos 5:11)
