Replace it with one where people have a say and not a ruling class?
You want everyone to vote on every issue? Because outside of that, we've already got that system you talk about.
There’s enough anarchist/communist/leftist literature out there discussing these issues, they’re not new
And those systems have flaws in them as well. It's not like rich and powerful means "Oh no, I cannot learn to exploit a new system!"
And the idea that you can vote your way out of this mess is adorable, naive, but adorable
See there's not an "out", that's where you've got it wrong. There's never a point where people stop pushing back on rich and powerful. That's literally the human condition, it's forever, always, until the heat death of the universe, an uphill. There is no top of the hill. There is no "out". Democracy is not a spectator sport, it requires all of us to continually and forever until the last of us is gone, fight the indoctrination with education, fight the power grabs with justice, and fight greed with humility.
At no point do we make progress by breaking laws and further showing how irrelevant that sheet of paper we call the Constitution is and rewriting it to be communist or foregoing it to be anarchist do not make it where suddenly human proclivities cease existing. You cannot do off with the evil side of human nature by adopting some magical means to live one's life and govern one's society. It is only with an enteral effort or the cessation of humanity itself that it can placed in check.
No you have all of this completely wrong. There is never "out".
