We do have this. Have you ever tried to raise money or interacted with VCs? Or dealt with the CEO of a large company? There is definitely a class divide. Look at all of the high end liberal arts students that monopolize the media industries. These aren't people from the trailer park.
"When you look at the fact that money is considered speech and the top .001 of the US makes as much every year as the bottom 80% of the country there is no way that even the amalgamated voices of the bottom 80% could hope to have the same political sway as those with money and this divide is only getting worse"
Except they were able to do this as per my example with Trump. Your theory sounds very valid, but the reality of it was the upper classes and all of their media empires couldn't stop someone from being elected. I think we can thank the internet for giving voice to those who historically wouldn't have it.
