This hints at the ideological chicken and egg problem here - wealth centralization breeds power centralization which breeds state corruption. The corruption of power through centralized wealth is presented as defenders of such wealth as an indicator of the states inability to impartially control such corruption.

The trick is the corruption already happened. The money was already too centralized, and has already done damage to the integrity of public institutions. That however is not a reason to abandon such institutions in favor of the monied interests that brought about the corruption, it is a reason to more seriously pursue means to purge the corruption and restore democracy. When that centralization of wealth causes that corruption, that means you need to address that vector in your ideology and policy goals as a citizen.

Ignoring it is just a long term means to eventually collapse the society as a self sustaining growth of both inequality and corruption consumes all prosperity and growth.
