objective is how rich are you as a country

even in china where some routes doesn't make sense to take plane...dominated by HSR, still can lose money, still need bailout
even in taiwan..this is literally the most successful one i saw, north to south with insane frequency everyday...almost every trip is full, still lose money

so the real question to ask is are you rich enough to keep bailout or not, if the answer is yes...thn build it
