Keyword is more just. I don't pretend I have an answer, there are people far more knowledgeable on these matters. IMO the key points would be something like decreasing the overall power of the government (and red tape) and moving towards more self representation. Voting from your IOT device is technically pretty feasible at this point (maybe check the link in my profile). Also, I feel nepotism and corruption might be reduced if positions of power (even potus) would be selected from the general citizen pool randomly (~like a jury) instead of campaigning for them. I'm not American but following the election I could not pick a candidate from any of the parties who I would trust to represent my views.
I guess these points are easily debatable according to personal taste, but I'm sure there are many better ideas around.
I agree voting from your IOT device is something that should happen. We will get there some day.
To get to that point sooner, we should elect more people who are knowledgeable about technology. If you disagree or feel that is an impossible route, you may be able to find others who feel similarly. Personally I think people who feel this way are part of a minority and that limiting your interactions to a certain group is isolating and not productive. I am always looking for ways to engage people with different ideas, both to learn and to share what I've learned.
Ultimately, I reject vox_mollis comment that participation in the democratic process is worthless or powerless. Just listen to This American Life's episode on "Take the Money and Run for Office" [1],
> Barney Frank: If the voters have a position, the votes will kick money's rear end any time. I've never met a politician-- I've been in the legislative bodies for 40 years now-- who, choosing between a significant opinion in his or her district and a number of campaign contributors, doesn't go with the district.

Or look at how Lindsey Graham changed his mind in the encryption case [3]. Our representatives are not entirely useless. Similar to your day job or at your school, some people are good at what they do, and some are bad at it. That's no reason to throw the baby out with the bath water. We have the longest running democratic republic in the world. We should study it, contribute improvements by speaking up and voting, and be proud of it. Much of the rest of the world faces strict repercussions when they even speak against their government.
