That's direct democracy.
If you ask me, people as a majority don't always know what is best. A lot of the biggest human advances wouldn't have happened because the masses would never have voted them. We need Representatives because they can make unpopular decisions for the good of the people.
What I think does need to change though, is this concept of parties. You vote for a representative, and they don't really represent you. They represent their parties. So you end up having to pick between very few (in many countries only two) parties that are probably all heavily influenced by lobbyist.
I guess you could say that political landscapes are centralised, and need to be decentralized.
