That would mean that Taiwan is currently paying virtually 100% of its defence budget on personnel costs. That clearly cannot be the case, otherwise Taiwan wouldn't be able to pay for any of the military equipment that hasn't just been ordered but is also arriving/being produced there. It wouldn't even be able to pay for fuel.With a desired end strength of 170,000-190,000, that's going to be about 2% of GDP in personnel costs.
The UK's GDP per capita is about £30,000. We do not spend £45,000 to £60,000 on our military personnel. Privates earn £20,000 a year and Sergeants £35,000. Even if you factor in equipment and training, that doesn't come close to the sums you're imagining.To pay for a professional military, you generally need to spend about 150-200% of GDP per capita per person.
I mean, I hear that in the US the cost of maintaining personnel is very high. Perhaps it's just a thing for a number of countries where there's too much money sloshing around and people don't think carefully enough about what's necessary and what's not. Relatively speaking a lot of US personnel are treated as kings and queens with access to all sorts of luxuries on their doorsteps, whereas their British counterparts have to make do with a lot less (and always have done).
