I feel that the American constitution is among the closest to ideal as the world has seen but, unfortunately, it's been bastardized by crooked politicians and special interest groups.

Another way forward? I think we need to better balance economic growth with caring for our environment. We also need to eliminate lobbying and have term/age limits for our politicians. We need to balance the wisdom age offers with young and fresh new ideas. Politicians simply should not have benefits for life after their term has ended and their families should be forced to use public healthcare and public schools in the districts they serve.

Also, candidates should not be able to purchase campaign ads of any kind, all candidates should be given an equal amount of air-time to spell out what they intend to do. If elected, they should be forced to give detailed progress reports on how many of their campaign promises they've achieved. If they aren't accomplishing their goals sufficiently they should be able to be voted out midway through their term. This would get them to focus on doing their jobs instead of shirking their duties and just focusing on raising money for their next campaign.

All this might be a good start.
