When i spend $80,000 on a car i do an effective CBA - at least in my head or on paper.
when i spend $5 on a burger i dont give it a second thought.
SCALE does affect things.
You spend $80,000 on a car? OMG...you're not one of those 65 year old mid-life crisis 30km/hr Mercedes drivers are you? Help.
I'm happy you mentioned that you do a CBA in your head or on paper. I'm sure most of us do the same thing: where we can appreciate in our heads the benefits of new infrastructure, especially when it has to do with technology. Like you said, not all CBA's should be done on paper, and some are just common sense.
hardly... a 46yo (when i got my FPV-GT) and i am the other end of the 30km/hr brigade.
when u r spending $43B... doing a CBA in ur head is unacceptable. plus when i am spending $80,000 on a car i am spening my money, and my money alone. if i was spending my company's money - ie not ALL my own money - a proper CBA woudl be done. and in this case the car would not be bought. How you can compare $80K and $43B is beyond me!
because money's worth is relative.
For me, $80,000 is is 1.14 my income. It's a LOT of money for me.
For a government, $37,400,000,000 is 0.17 their annual revenue (taking 05/06 listing from a quick google search). Now..I'm not 100% sure but it isn't a one lump sum. If we are to spread it over the lifetime of the project... 4.16 billion per year over 9 years. Hence it's 0.02 of annual revenue per year for 9 years.
Now, comparing that back to me... that's $1400. $26 per week.
What were you saying about not caring for paying for a burger?
Relative.
PS: Take this as light humour, obviously.
It is of course a joke your post.
The give away was when you mislaid your decomal point, with your calcualtion of $37.4 billion being only 0.17 of annual revenue of around $295 billion.
You meant to say 17% (actually it's closer to 13%), but you tried to downplay the real percentage.
