I consider “at least some of the time” to be an argument in favor of the opposite position. Beside, a public corporation also “sometimes” does what’s best for their consumers/user (when it aligns with the best interests of the shareholders, instead of the keys to democratic power).
I don’t consider myself sufficiently informed about whole countries. Sure America isn’t China but as an ally country… I worry. First past the post and an electoral college are not a voting system which can provide people significant representation in government. If any elected American has the majority of the people’s best interests at heart, that is luck because it’s not by design.
Everyone representing themselves is an extreme example but hopefully clearly shows how more representatives are better at representing a group than fewer. Compare a voting result of 50% A, 25% B, 25% C with a system that gives you 1 representative (from A) with a system that gives you 5 representatives (3 from A, 1 from B, 1 from C).
Electoral college permit states to choose electors who can cast their vote in a way that doesn’t reflect how people in their state voted for. If a critical amount of states agree they can choose to make the overall result better represent nationwide what all Americans voted for (an election of an election results in a bigger misrepresentation error).
