It's hard to build up to complex solutions when we (society, broadly defined) seem unable to agree on the basic facts.
I don't know for sure if the past was better or worse when it came to reporting the truth. Given the limited number of news outlets, radio stations and tv stations historically, there were at least a limited set of reporting to agree on (independent of the accuracy of that reporting). This was probably very helpful in enabling more complex solutions.
Every complex solution will add an additional layer of complexity on top of everything, thereby making the problem worse. If society, as a whole, becomes so complex that the processes that keep it rolling are no longer transparent, then we'd end up in a situation where we can't see the forest for the trees.
The list of objective facts regarding any major issue is short. The list of subjective facts is infinite. When anyone can blast the world with their subjective facts, the objective facts are lost in the noise.
It's not one, though.
