Thank you, Benjamin,
Yes, I came here as an immigrant almost 30 years ago, and within a year I recognized that the voting system helped push many problems away from the decision makers, who were vying to win the majority and were not interested to rule the country for all.
Here is an image I discovered in a book on politics. I colored in the forms of election format.
Some nations require folks to vote, so that distorts the outcome. But the overall idea should be obvious: when voting in districts, more people stay home because their choices are limited, and after four times getting nothing, many folks don't show up the fifth time.
You are right that we need to get the right voting system for the right places. At the local level, there is never a reason to limit voter rights. For large nations, we both agree that keeping some stability is important.
A color copier has three colors and black to do everything it needs to print full-color. I think a four-party system is all a large nation needs to put in place to deliver what we can call political freedom.
Anything more and it invites instability no large nation needs when times are rough. Anything less, and voter suppression is then automatically included and domination and regulation of society is then in the hands of a few (“1984” came to mind when I immigrated into the US, that book was far more real than I ever imagined; I thought it was based on communist nations until I moved here and recognized the limited freedom in the US).
