I agree on a perfect world scenario, but we in Russia have a big pile of ridiculous court decisions every month.
I would point out that the conviction ratio of the US is indicative of massive flaws in the powers that DAs have in most jurisdictions to force time limited plea agreements on defendants who have limited information and are under threat of charges with much higher penalties. This can usually be done without any oversight or approval from judges.

That sounds like a world with complete surveillance, no privacy and a judicial system with absolute power. Doesn't sound like a perfect world to me.
Just wanted to note that it is not a very good way to gauge opressiveness or fairness... In a perfect world, charges would only ever be brought against the guilty, and only the guilty would be found as such by court. In such a World the ratio would be 0:<division by zero error>...
