Most of this entire discussion is missing the point. On the one hand a variety of views and/or options for political representation are needed. This is where first past the post utterly fails. It devolves mostly to a two choice system, as is becoming painfully obvious in the US. Or it might become unstable/unpredictable as seen in the UK where alternative parties are emerging, but probably to the detriment of the old parties. In the end it might well devolve back to a two party system, just two other parties. This is where some form of proportional representation system comes in. More than two parties are viable. But at the cost of stability. Back in schooly politics teacher liked to present Italy as the poster child for why (simple) PR doesn’t work well. Though in recent years the Italian government has proven quite stable. Also, in Italys Case I’d love to run the experiment how they did with nothing changed except for organized crime being eradicated. Alas, in humanities controlled experiments like that aren’t possible. But I’d not be surprised if spectacular corruption wasn’t the bigger problem.
So what could the solution be? First I’d like to see corruption stomped out completely. I know, that’s almost like wishing for world peace, and come to think about it, it’s mostly the same characters that are in the way. Second, the solution is likely to be neither a simple majority system nor a simple proportional system. Ranked choice? My teacher was taken by the German system (a mixture of both), but that has it’s own problems. Or something entirely different, like completely independent publicly funded media. Print, audio and audiovisual. And that media could run regular polls to publicly show which topics are important to people.
I think our problems stem more from the influence on populations rather than the actual modality in which our representation is formed. In Israel you have the corruptive influence of ultra-orthodox and nationalist hardliners mixed with some run if the mill corruption, in Italy you have a gigantic organized crime problem, with some rich people problem, in Germany the Springer group is trying to set up a Fox news situation and in the US you have the Fox/Heritage Foundation/billionaires and general corruption through money problem.
But it very much depends on what you count as a language. German used to be a dialect continuum. People could understand their neighbors and a village or two over, but became mutually unintelligible pretty quickly. Transportation was slow, so populations just didn’t mix as much and language was more local. Latin used to mostly be the language of a single city.
