So many flavours of duopoly, some meaningful, some merely two cheeks of the same oligarchy arse. Over decades, politics and power centralizes at the top and, in democracies, evolves concurrently to subordinate suffrage to the needs of stable continuity – by polarizing electorate into opposing echo chambers kept busy chasing a public conversation driven by the appearance of distinct opposing blocs (parties). Team politics. Identity politics. Orthodox legitimacy over heterodox insurgency. Democracy becomes a pressure valve, a litmus for improved crowd control by permanent ruling elites rather than a crucible for testing competing ideas that might best serve the needs of the people.
Perhaps like communism leads ultimately to totalitarian despotism, corporate capture may be the inevitable coda for neoliberal monopoly capitalism. Contemporary western society certainly bears out the analysis.
