Have you read the study insinuating that the United States is an oligarchy?
Here is the article I read, from BBC.
and here is the study itself.
From the study:
“Multivariate analysis indicates that economic elites and organised groups representing business interests have substantial independent impacts on US government policy, while average citizens and mass-based interest groups have little or no independent influence.”
“When a majority of citizens disagrees with economic elites and/or with organised interests, they generally lose. Moreover, because of the strong status quo bias built into the US political system, even when fairly large majorities of Americans favour policy change, they generally do not get it.”
”...we believe that if policymaking is dominated by powerful business organisations and a small number of affluent Americans, then America’s claims to being a democratic society are seriously threatened.”
