We can deduce here that the line from the passage that best supports the idea that money corrupts government is: "[Men] honor and look up to the rich man, and make a ruler of him."
<h3>What is a main idea?</h3>
Main idea actually refers to the central lesson or important message that an excerpt, passage, a line or a story is carrying. It refers to the message that the author wishes to pass across to the audience.
We see here that the passage that completes the question is:
The accumulation of gold in the treasury of private individuals is the ruin of timocracy [a state where only property owners can participate in government]; they invent illegal modes of expenditure; for what do they or their wives care about the law? . . . . And then one, seeing another grow rich, seeks to rival him, and thus the great mass of the citizens become lovers of money. . . . And so at last, instead of loving contention and glory, men become lovers of trade and money; they honor and look up to the rich man, and make a ruler of him, and dishonor the poor man.
Thus, the line that best supports the idea that that money corrupts government is "[Men] honor and look up to the rich man, and make a ruler of him."
