Not sure to be honest. Only pacifist country in the world so no military cost. However it is very socialist and has big social policy stuff that costs a lot and the actual income tax is not that high really. Top bracket 25% I think. A rico friend explained it like this “you want to live a relatively simple life, tax is low, you want luxuries, you pay more tax and that’s what’s used to help bump up budget for health care for all and stuff so the system is geared that those who consume more, pay more”

Personally, I think the complexity and high level of import duties holds the country back quite a lot.
