What type of government made the rich rich and the poor poorer?

Governments characterized by extreme capitalism or oligarchy often exacerbate income inequality, making the rich richer and the poor poorer. In these systems, wealth and power are concentrated in the hands of a few, often through policies that favor large corporations and wealthy individuals at the expense of social welfare programs and equitable economic opportunities. Additionally, corruption and lack of regulation can further entrench this disparity, limiting upward mobility for the disadvantaged.
