Do you think if the people of Earth could choose their own candidates for Parliament/elections instead of the political parties (if they didn't already somewhere), there would be less chaos in the planet's democracies?

Take USA, for example. There’s been for as long as we can remember conflict between Republicans and Democrats. As far as I know, others with their own party weren’t even remotely considered as worthy of the GOP and GDP’s time. I say, the people SHOULD vote their own candidates for the election, and for the parliament itself.
