Other places haven’t come anywhere near the politicisation that the US has. Instead, appointments are treated as pretty meritocratic.

I’ve personally spoken to a former chief justice of a country about the selection process, and they said unequivocally that it should be taken away from the government. It should instead be done by an intermediate selection committee whose members are selected by the government. Basically creating a degree of separation between the government and the court to buffer against politicking the whole thing.

Makes perfect sense to me and is probably the best chance the US has apart from packing the court.

Otherwise, without knowing much about the US situation, it seems to be in part attributable to the polarisation of the strict two party system, the central quasi-monarchical presidency and the vagueness and ~~hear~~heat of the bill of rights. Lots of places just don’t have that combination of factors … where in same ways the US system is likely showing its age and lack of evolution over time.

In fact, generally, it might be true to say that US politics over the past 10 years and into the next century will be driven by the friction between needing to adapt to its new state in the world (less super power and more dependent on global affairs) and wanting to cling to its traditional role and the old promises of the post-war era.
