I don’t know why it has taken so long for someone in power to popularise the broken nature of the US political system. Many have tried to do this in the media, most notably Michael Moore in Bowling for Columbine and then Sicko.
Corporate lobbying is legalised corruption. Of that, I am sure. Here, Ocasio-Cortez does a really good job of showing this, and implying that the President is the baddest of all them apples.
Here is the (time linked) scene from Sicko that does a really good job of showing how compromised US politicians are.
