Final answer:
Most of the poor citizens became poorer under the rule of oligarchs.
Step-by-step explanation:
The rule of oligarchs had a negative impact on most of the poor citizens. Instead of becoming wealthier, they actually became poorer. As the political elite lost control of wealth and power to the business elite, many ordinary workers faced unemployment as companies downsized. Moreover, private ownership of housing led to skyrocketing housing costs, making it difficult for many people to afford homes or condos.
