And shit on the US all you want. It’s a terrible system controlled by corporations and the only people that believe who they vote for matters are dimwits that believe the bullshit pedaled to them by the media. I just think you should also understand that the reality of your ideal is no better. It’s just different branding of the same control by those at the top.
There have been some material pointed at you for reading already, so I just want to say that this is just common liberal thinking used to discredit any attempt of change by claiming everything is the same, "it's all different power hungry elites at the top" stuff.
That's a fundamentally wrong view of how societies work that not only completely ignores class struggle, also ignores all the advancement made in socialist societies. You are already on the right path and identified that the US is controlled by corporations, you just gotta go further and realize these corporations have owners, the extremely wealthy, the capitalist class. From there you can start to understand the interests a government serves under a capitalist society. That's not to say there haven't been any mistakes and wrongdoings in socialist societies, far from that, we are very aware of that and self-critique is core to communist thought.
With all that said, there isn't much I can add here that will convince you or anything, this is something that takes willingness, time and research. What I can ask of you is to at least give it a fair thought. If you want good starting places in a video format in english, give Second Thought, Hakim and Yugopnik a watch from time to time.
