United States of Ameria is an oligarchy. This is based on a study that I've been sharing every now and then.
Esteemed researchers Martin Gillens and Benjamin Page at Princeton University took 1779 policy issues, found out what the richest 1,1% thought about them, what special business-interest groups thought about them, what the average voter thought about them and what mass-based organization thought about them. Then they looked at what bills passed and which didn't.
They found "that Economic elites and organized groups representing business interests have substantial independent impacts on U.S. government policy, while average citizens and mass-based interest groups have little or no independent influence."
This means that it is a fact that your opinion as a voter doesn't matter.
If you're going to try to educate yourself on politics to better your vote, you are wasting your time. Get over it.
The side you helped may win the election but it wasn't on your side.
The study confirms what many democracy critics have known for a while: Organized greed almost always wins disorganized public interest:
