I’ve heard a lot of Australians complain about politics there. Maybe that’s just because people complain about politics everywhere.

i think this is true no matter what: nz and germany are both more proportional systems and similarly people dislike politics

it also seems like Australia has a lot of problems that aren’t getting solved (like housing cost).

absolutely… some problems are incredibly tricky: getting people to vote against their interests (eg with housing, any effort to reduce house prices directly decreases the value of peoples assets - perhaps not investments, but their primary home even)

how to achieve some societal good things is really tricky in any democracy i think
