Imagine a contract case where the issues are in plain text, black and white, but the Judge won't even look at the contract until the process of discovery is complete and you've racked up a year's worth of legal bills.
This is an interesting read, and things have gotten no better since 1987; they've gotten much worse: https://scholarship.law.missouri.edu/cgi/viewcontent.cgi?art...
In China, I don't believe that there was any discovery process -- perhaps there was something that the lawyers did behind the scenes, but it was certainly nothing like it is in America. Cases go before judges fast, and then they go to trial fast, and they generate less useless paper. (And fewer billable hours.) It can be as little as 6 months from start to finish.
