Because the US has first past the post. Sure you could vote for someone who matches every single one of your ideologies, but the chance that they win is zero.

Is there a country that does it better? I can't think of one. Voting on people seems what's being done everywhere, and the source of this problem.

Ergo: need a better system

But first past the post already works...

...for the people who would need to vote to change it.

They ain't gunna change something that will work against them after they change it...

Yea, you nailed it.

I'm not sure you are attacking representative democracy, but instead are attacking the US two party system. I'm def not going to argue against you on that. Just wanted to say that in a representative democracy, one does have a say in policy. I do very much agree that the US tries to give us all as little of a say as possible, as the "adults" (read: billionaires) decide things for us
